The manpage of uscan is very confusing ...
So I made a fresh new manpage using POD for easy updates.
Patches are against GIT master HEAD.
I also added few test cases which I used to check uscan behavior while
writing this manpage.

+=head1 NAME
+
+uscan - scan/watch upstream sources for new releases of software
+
+=head1 SYNOPSIS
+
+B<uscan> [I<options>] [I<path>]
+
+=head1 DESCRIPTION
+
+For the basic usage, B<uscan> is executed without any arguments from the root
+of the Debianized source tree where you see the F<debian/> directory.
+Then typically the following happens:
+
+=over
+
+=item * B<uscan> downloads the upstream tarball with the highest version from
+the remote URL specified in F<debian/watch>
+
+=item * B<uscan> reads the first entry in F<debian/changelog> to determine the
+source package name I<spkg> and the last upstream version.
+
+=item * B<uscan> saves the downloaded tarball to the parent B<../> directory:
+I<< ../<upkg>-<uversion>.tar.gz >>
+
+=item * B<uscan> invokes B<mk-origtargz> to create the source tarball: I<<
+../<spkg>_<sversion>.orig.tar.gz >>
+
+=item * B<uscan> invokes B<uupdate> to create the Debianized source tree: I<<
+../<spkg>-<sversion>/* >>
+
+=back
+
+Here, B<uscan> allows extensive flexibility. The upstream tarball in he remote
+URL can be F<http://www.example.org/download/foo-v1.0.tar.gz>, the downloaded
+tarball can be F<../foo-1.0.tar.gz>, the source tarball can be
+F<../bar_2.1.0.orig.tar.gz>, and the Debianized source tree can be located at
+F<../bar-2.1.0>.
+
+Note: For simplicity, the compression method used in examples is B<gzip> with
+B<.gz> suffix. Other methods such as B<xz>, B<bzip2>, and B<lzma> may also be
+used.
+
+=head1 FORMAT OF THE WATCH FILE
+
+The current version 3 format of F<debian/watch> can be summarized as follows:
+
+=over
+
+=item * Leading spaces and tabs are dropped.
+
+=item * Empty lines are dropped.
+
+=item * A line started by B<#> (hash) is a comment line and dropped.
+
+=item * Single B<\> (back slash) at the end of a line is dropped and the the
+next line is concatenated after removing leading spaces and tabs.
+
+=item * The first non-comment line is:
+
+=over
+
+=item B<version=3>
+
+=back
+
+This is required.
+
+=item * The second non-comment line specifies the rule for the candidate
+upstream tarball URL and is typically in the following format:
+
+=over
+
+=item [B<opts="> I<...> B<">] \
+
+=item B<http://>I<URL> \
+
+=item I<matching-pattern> \
+
+=item [B<debian> [B<uupdate>]]
+
+=back
+
+Here, lines are folded with B<\> for readability. You may write this in a
+single line. A space before each B<\> is significant. B<[> and B<]> are there
+to mark optional parts and should not be typed.
+
+The last 2 entries, B<debian> and B<uupdate>, are completely optional. If these
+are missing, these are the default values for the Debian non-native source package.
+
+There are 2 other F<debian/watch> formats which concatnate B<http://>I<URL> and
+I<matching-pattern> with B</>. One for HTTP and another for FTP. See
+L<ADVANCED FEATURES>.
+
+=back
+
+=head1 TYPICAL EXECUTION
+
+Let's describe step-by-step how B<uscan> processes this typical F<debian/watch>
+.
+
+B<uscan> reads the per-site option specified in B<opts="> I<...> B<"> to
+customize its behavior. They are:
+
+=over
+
+=item * The mangling rules which apply the I<rule> to the pertinent I<string>.
+They behave as if a Perl command "I<$target_string> B<~=> I<rule>" is executed.
+
+=over
+
+=item * B<dversionmangle=>I<rule> for the last upstream version string found in F<debian/changelog>
+
+=item * B<uversionmangle=>I<rule> for the candidate upstream version strings
+
+=item * B<versionmangle=>I<rules> as a syntactic shorthand for:
+
+B<uversionmangle=>I<rules>B<,dversionmangle=>I<rules>
+
+=item * B<filenamemangle=>I<rule> for the downloaded tarball filename string
+
+=item * B<downloadurlmangle=>I<rule> for the candidate upstream tarball URL string
+
+=item * B<pgpsigurlmangle=>I<rule> for the candidate upstream signature file URL string
+
+=back
+
+=item * B<pasv> option for the FTP connection to use PASV mode. This is
+recommended for most cases using the FTP connection.
+
+=item * B<repacksuffix> option for the version suffix used by the repackaged
+source tarball
+
+=back
+
+See L<Details of per-site options> for the details.
+
+B<uscan> reads the first entry in F<debian/changelog> to determine the source
+package name and the last upstream version.
+
+For example, if the first entry of F<debian/changelog> may be:
+
+=over
+
+=item I<sourcepackage> (B<3:2.03+dfsg1-4>) unstable; urgency=low
+
+=back
+
+then, the source package name is I<sourcepackage> and the last upstream version
+is determined to be B<2.03+dfsg1> without the epoch and the Debian revision.
+
+If the B<dversionmangle> rule exists, the last upstream version is updated by
+applying this rule to it. For example, if the last upstream version is
+B<2.03+dfsg1> indicating the source tarball is repackaged, the suffix B<+dfsg1>
+is removed by the string substitution B<s/\+dsfg\d*$//> to make the
+(dversionmangled) last upstream version B<2.03> and it is compared to the
+candidate upstream tarballs such as B<2.03>, B<2.04>, ... . Thus, set this
+rule as:
+
+=over
+
+=item B<opts="dversionmangle=s/\+dsfg\d*$//">
+
+=back
+
+B<uscan> downloads a web page from B<http://>I<URL> specified in
+F<debian/watch>.
+
+=over
+
+=item * If the directory name part of I<URL> has no parentheses, B<(> and B<)>,
+it is taken as verbatim.
+
+=item * If the directory name part of I<URL> has parentheses, B<(> and B<)>,
+then B<uscan> recursively searches all possible directories to find a page for
+the newest version.
+
+=back
+
+For example, this B<http://>I<URL> may be specified as:
+
+=over
+
+=item * B<http://www.example.org/DL(.+)/>
+
+=back
+
+Please note the trailing B</> in the above.
+
+The downloaded web page is scanned for links defined in the B<< <a href=" >>
+I<...> B<< "> >> tag to locate the candidate upstream tarball URLs. These
+candidate upstream tarball URLs are matched by the Perl regex pattern
+I<matching-pattern> such as B<DL-(?:[\d\.]+?)/upstreamname-(.+)\.tar\.gz> to
+narrow down the candidates. This pattern match needs to be anchored at the
+beginning and the end. For example, candidate URLs may be:
+
+=over
+
+=item * B<DL-2.02/upstreamname-2.02.tar.gz>
+
+=item * B<DL-2.03/upstreamname-2.03.tar.gz>
+
+=item * B<DL-2.04/upstreamname-2.04.tar.gz>
+
+=back
+
+Here the matching string of B<(.+)> in I<matching-pattern> is considered as the
+candidate upstream version. If there are multiple matching strings of
+capturing patterns in I<matching-pattern>, they are all concatenated with B<.>
+(period) to form the candidate upstream version. Make sure to use the
+non-capturing regex such as B<(?:[\d\.]+?)> instead for the variable text
+matching part unrelated to the version.
+
+For example, candidate upstream versions may be:
+
+=over
+
+=item * B<2.02>
+
+=item * B<2.03>
+
+=item * B<2.04>
+
+=back
+
+The downloaded tarball filename is set to the same as its filename in the
+remote URL.
+
+If the B<uversionmangle> rule exists, the candidate upstream versions are
+updated by applying this rule to them. (This rule may be useful if the
+upstream tarball needs to be repacked.)
+
+The upstream tarball URL corresponding to the newest (uversionmangled) candidate
+upstream version newer than the (dversionmangled) last upstream version is
+selected to be the candidate upstream tarball URL.
+
+Here, the order of the version is decided by B<dpkg --compare-versions>.
+
+If the B<filenamemangle> rule exists, the downloaded tarball filename is
+updated by applying this rule to it. (This rule may not be significant for
+modern use cases. B<mk-origtargz> takes care proper naming of the source
+tarball based on the source package name in F<debian/changelog> without relying
+on the filename of the remote URL. B<uupdate> is invoked by B<uscan> with
+B<--no-symlink> option and does not rename the tarball anymore.)
+
+If the candidate upstream tarball URL is a relative URL, it is converted to a
+absolute URL using the base URL of the web page. If the B<< <base href=" >> I<
+... > B<< "> >> tag exists in the web page, the candidate upstream tarball URL
+is converted to the absolute URL using the specified base URL in the base tag,
+instead.
+
+If the B<downloadurlmangle> rule exists, the candidate upstream tarball URL is
+updated by applying this rule to it. (This is useful for some sites with the
+obfuscated download URL.)
+
+B<uscan> downloads the candidate upstream tarball to the parent B<../>
+directory. For example, the downloaded file may be:
+
+=over
+
+=item * F<../upstreamname-2.04.tar.gz>
+
+=back
+
+Let's call this B<2.04> in the above example generically as I<version> in the
+following.
+
+If the B<pgpsignurlmangle> rule exists, the upstream signature file URL is
+generated by applying this rule to the (downloadurlmangled) candidate upstream
+tarball URL and the signnature file is tried to be downloaded.
+
+Otherwise, 4 common possible upstream signature file URLs are tried by
+appending 4 common suffixes B<.asc>, B<.gpg>, B<.pgp>, and B<.sig> to the
+(downloadurlmangled) candidate upstream tarball URL and at least one signature
+file is tried to be downloaded.
+
+If the downloaded signature file exists, the downloaded upstream tarball is
+checked for its authenticity using the downloaded signature file by using the
+keyring F<debian/upstream/signing-key.pgp> or the armored keyring
+F<debian/upstream/signing-key.asc>. If it is not valid, or not made by one of
+the listed keys, B<uscan> will report an error.
+
+B<uscan> invokes B<mk-origtargz> to create the source tarball properly named
+for the source package with B<.orig.> in its filename.
+
+=over
+
+=item case A: package the upstream tarball as is
+
+B<mk-origtargz> creates a symlink
+B<../>I<sourcename>B<_>I<version>B<.orig.tar.gz> linked to the downloaded local
+upstream tarball. Here, I<sourcename> is the source package name found in
+F<debian/changelog>. For example, if I<sourcename> is B<foo>, the generated
+symlink may be:
+
+=over
+
+=item * F<../foo_2.04.orig.tar.gz> -> F<upstreamname-2.04.tar.gz> (as is)
+
+=back
+
+Usually, there is no need to set up B<opts="dversionmangle=> I<...> B<"> for
+this case.
+
+=item case B: package the upstream tarball aftre removing non-DFSG files
+
+B<mk-origtargz> checks the filename glob of the B<Files-Excluded> stanza in the
+first section of F<debian/copyright>, removes matching files to create a
+repacked upstream tarball. Normally, the repacked upstream tarball is renamed
+with I<suffix> to B<../>I<sourcename>B<_>I<version>I<suffix>B<.orig.tar.gz>
+using the B<repacksuffix> option. Here I<version> is updated to be
+I<version>I<suffix>.
+
+The removal of files is required if files are not DFSG-compliant. For such
+case, B<+dfsg1> is used as I<suffix>.
+
+So the combined per-site options are set as
+B<opts="dversionmangle=s/\+dsfg\d*$// ,repacksuffix=+dfsg1">, instead.
+
+For example, the repacked upstream tarball may be:
+
+=over
+
+=item * F<../foo_2.04+dfsg1.orig.tar.gz> (repackaged)
+
+=back
+
+=back
+
+B<uscan> normally invokes "B<uupdate> B<--no-symlink --upstream-version>
+I<version> B<../>I<sourcename>B<_>I<version>B<.orig.tar.gz>".
+
+Please note that B<--no-symlink> option is used here since B<mk-origtargz> is
+invoked to make B<*.orig.tar.gz> file ready to be used for the source package.
+B<uscan> picks I<sourcename> from F<debian/changelog> so the tarball filename
+of the actual remote URL does not matter for packaging.
+
+It creates the new upstream source tree under the
+B<../>I<sourcename>B<->I<version> directory and Debianize it leveraging the
+last package contents.
+
+=head1 ADVANCED FEATURES
+
+B<uscan> has many other enhanced features which are skipped in the above
+section for the simplicity. Let's check their highlights.
+
+B<uscan> actually scans not just the current directory but all its
+subdirectories looking for F<debian/watch> to process them all.
+See the below section L<Directory name checking>.
+
+B<uscan> can be executed with I<path> as its argument to change the starting
+directory of search from the current directory to I<path> .
+
+B<uscan> can be used to assess the health of the package by executing with
+B<--report> option to output a human readable report without downloading the
+upstream tarball.
+
+B<uscan> can be used to assess the health of the package by executing
+with B<--dehs> option to output an XML data suitable for the DEHS system.
+
+B<http://>I<URL> part in the second non-comment line can be B<https://>I<URL>
+to use the SSL/TLS protocol, instead
+
+The second non-comment line of F<debian/watch> can be in the alternative
+formats.
+
+=over
+
+=item * If I<matching-pattern> does not contain B</>, a short hand format may
+be used:
+
+=over
+
+=item [B<opts="> I<...> B<">] \
+
+=item B<http://>I<URL/matching-pattern> \
+
+=item [B<debian> [B<uupdate>]]
+
+=back
+
+Here, B<http://>I<URL> is accessed for the web page.
+
+=item * If the FTP protocol is used instead of HTTP/HTTPS, the following format should be used:
+
+=over
+
+=item [B<opts="> I<...> B<">] \
+
+=item B<ftp://>I<URL/matching-pattern> \
+
+=item [B<debian> [B<uupdate>]]
+
+=back
+
+It is good idea to set B<opts=pasv> here which makes B<uscan> try the passive FTP protocol first.
+
+=back
+
+The optional B<debian> string in the second non-comment line of F<debian/watch>
+means to obtain the last upstream version from F<debian/changelog>. If this is
+replaced by a specific version number such as B<1.0.2>, B<1.0.2> is used as the
+last upstream version, instead.
+
+The optional B<uupdate> string in the second non-comment line of
+F<debian/watch> means to execute B<uupdate> with options after processing this
+line. For example, you can customize this by replacing B<uupdate> by
+F<debian/myuupdate> with the following content.
+
+ #!/bin/sh -e
+ # called with '--upstream-version' <version> <file>
+ uupdate "$@" --no-symlink
+ package=`dpkg-parsechangelog | sed -n 's/^Source: //p'`
+ cd ../$package-$2
+ debuild
+
+Then B<uscan> invokes "I<debian/myuupdate> B<--upstream-version> I<version>
+B<../>I<sourcename>B<_>I<version>B<.orig.tar.gz>" instead to perform a fully
+automatic upstream update of Debian binary packages.
+
+Note that we don't call B<dupload> or B<dput> automatically, as the maintainer
+should perform sanity checks on the software before uploading it to Debian.
+
+See L<OPTIONS> and L<CONFIGURATION VARIABLES> for other variations.
+
+=head1 EXAMPLE
+
+Here are the typical F<debian/watch> files.
+
+The existance and non-existance of a space before tailing B<\> (back slash) are
+significant.
+
+=head2 HTTP site (basic)
+
+For the basic HTTP site:
+
+ http://example.com/~user/release/foo.html \
+ files/foo-([\d\.]*).tar.gz
+
+=head2 HTTP site (flexible)
+
+For the maximum flexibility of upstream tarball formats:
+
+ http://example.com/example-(\d[\d.]*)\.\
+ (?:zip|tgz|tbz2|txz|tar\.(?:gz|bz2|xz))
+
+=head2 HTTP site (recursive directory scanning)
+
+For recursive directory scanning:
+
+ http://tmrc.mit.edu/mirror/twisted/Twisted/(\d\.\d)/ \
+ Twisted-([\d\.]*)\.tar\.bz2
+
+or in one string style variant
+
+ http://tmrc.mit.edu/mirror/twisted/\
+ Twisted/(\d\.\d)/Twisted-([\d\.]*)\.tar\.bz2
+
+Here, the website should be able to handle requests to:
+
+ http://tmrc.mit.edu/mirror/twisted/Twisted/
+
+=head2 HTTP site (alternative)
+
+For one string style:
+
+ http://www.cpan.org/modules/by-module/Text/Text-CSV_XS-(.+)\.tar\.gz
+
+This is the same as
+
+ http://www.cpan.org/modules/by-module/Text Text-CSV_XS-(.+)\.tar\.gz
+
+=head2 HTTP site (sf.net)
+
+For SourceForge based projects, qa.debian.org runs a redirector which allows a
+simpler form of URL. The format below will automatically be rewritten to use
+the redirector.
+
+ http://sf.net/audacity/audacity-src-(.+)\.tar\.gz
+
+=head2 HTTP site (github.com)
+
+For GitHub projects, you can use the tags or releases page. The archive URLs
+use only the version as the filename. You can rename the downloaded upstream
+tarball into standard I<project>B<->I<version>B<.tar.gz> using
+B<filenamemangle>:
+
+ opts="filenamemangle=\
+ s/(?:.*?)?v?(\d[\d.]*)\.tar\.gz/<project>-$1.tar.gz/" \
+ https://github.com/<user>/<project>/tags \
+ (?:.*?/)?v?(\d[\d.]*)\.tar\.gz
+
+=head2 HTTP site (code.google.com)
+
+For Google Code projects, you should use the downloads page like this:
+
+ https://code.google.com/p/<project>/downloads/list?can=1 \
+ .*/<project>-(\d[\d.]*)\.tar\.gz
+
+=head2 HTTP site (funny version)
+
+For a site which has funny version numbers, the parenthesized groups will be
+joined with B<.> (period) to make a sanitized version number.
+
+ http://www.site.com/pub/foobar/foobar_v(\d+)_(\d+)\.tar\.gz
+
+=head2 HTTP site (DFSG)
+
+The upstream part of the Debian version number can be
+mangled:
+
+ opts="dversionmangle=s/\+dfsg\d*$//,repacksuffix=+dfsg1" \
+ http://some.site.org/some/path/foobar-(.+)\.tar\.gz
+
+=head2 HTTP site (filenamemangle)
+
+The filename is found by taking the last component of the URL and
+removing everything after any '?'. If this would not make a usable
+filename, use B<filenamemangle>. For example,
+F<< <A href="http://foo.bar.org/dl/?path=&dl=foo-0.1.1.tar.gz";> >>
+could be handled as:
+
+ opts=filenamemangle=s/.*=(.*)/$1/ \
+ http://foo.bar.org/dl/\?path=&dl=foo-(.+)\.tar\.gz
+
+
+F<< <A href="http://foo.bar.org/dl/?path=&dl_version=0.1.1";> >>
+could be handled as:
+
+ opts=filenamemangle=s/.*=(.*)/foo-$1\.tar\.gz/ \
+ http://foo.bar.org/dl/\?path=&dl_version=(.+)
+
+=head2 HTTP site (downloadurlmangle)
+
+The option B<downloadurlmangle> can be used to mangle the URL of the file
+to download. This can only be used with B<http://> URLs. This may be
+necessary if the link given on the web page needs to be transformed in
+some way into one which will work automatically, for example:
+
+ opts=downloadurlmangle=s/prdownload/download/ \
+ http://developer.berlios.de/project/showfiles.php?group_id=2051 \
+ http://prdownload.berlios.de/softdevice/vdr-softdevice-(.+).tgz
+
+=head2 FTP site (basic):
+
+ opts=pasv \
+ ftp://ftp.tex.ac.uk/tex-archive/web/c_cpp/cweb/cweb-(.+)\.tar\.gz
+
+=head2 FTP site (regex special characters):
+
+ opts=pasv \
+ ftp://ftp.worldforge.org/pub/worldforge/libs/\
+ Atlas-C++/transitional/Atlas-C\+\+-(.+)\.tar\.gz
+
+Please note that this URL is connected to be I< ... >B<libs/Atlas-C++/>I< ... >
+. For B<++>, the first one in the directory path is verbatim while the one in
+the filename is escaped by B<\>.
+
+=head2 FTP site (funny version)
+
+This is another way of handling site with funny version numbers,
+this time using mangling. (Note that multiple groups will be
+concatenated before mangling is performed, and that mangling will
+only be performed on the basename version number, not any path
+version numbers.)

+
+
+=head1 OPTIONS
+
+For the basic usage, B<uscan> does not require to set these options.
+
+=over
+
+=item B<--report>, B<--no-download>
+
+Only report about available newer versions but do not download
+anything.
+
+=item B<--report-status>
+
+Report on the status of all packages, even those which are up-to-date,
+but do not download anything.
+
+=item B<--download>
+
+Report and download. (This is the default behavior.)
+
+=item B<--destdir>
+
+Path of directory to which to download. If the specified path is not absolute,
+it will be relative to one of the current directory or, if directory scanning
+is enabled, the package's
+source directory.
+
+=item B<--force-download>
+
+Download upstream even if up-to-date (will not overwrite local files, however)
+
+=item B<--pasv>
+
+Force PASV mode for FTP connections.
+
+=item B<--no-pasv>
+
+Do not use PASV mode for FTP connections.
+
+=item B<--timeout> I<N>
+
+Set timeout to I<N> seconds (default 20 seconds).
+
+=item B<--no-symlink>
+
+Do not call B<mk-origtargz>.
+
+=item B<--dehs>
+
+Use an XML format for output, as required by the DEHS system.
+
+=item B<--no-dehs>
+
+Use the traditional uscan output format. (This is the default behavior.)
+
+=item B<--package> I<package>
+
+Specify the name of the package to check for rather than examining
+F<debian/changelog>; this requires the B<--upstream-version> (unless a version
+is specified in the F<watch> file) and B<--watchfile> options as well.
+Furthermore, no directory scanning will be done and nothing will be downloaded.
+This option is probably most useful in conjunction with the DEHS system (and
+B<--dehs>).
+
+=item B<--upstream-version> I<upstream-version>
+
+Specify the current upstream version rather than examine F<debian/watch> or
+F<debian/changelog> to determine it. This is ignored if a directory scan is being
+performed and more than one F<debian/watch> file is found.
+
+=item B<--watchfile> I<watchfile>
+
+Specify the I<watchfile> rather than perform a directory scan to
+determine it. If this option is used without B<--package>, then
+B<uscan> must be called from within the Debian package source tree
+(so that F<debian/changelog> can be found simply by stepping up
+through the tree).
+
+=item B<--download-version> I<version>
+
+Specify the I<version> which the upstream release must match in order to be
+considered, rather than using the release with the highest version.
+
+=item B<--download-current-version>
+
+Download the currently packaged version
+
+=item B<--verbose>
+
+Give verbose output.
+
+=item B<--no-verbose>
+
+Don't give verbose output. (This is the default behavior.)
+
+=item B<--no-exclusion>
+
+Do not automatically exclude files mentioned in F<debian/copyright> field B<Files-Excluded>
+
+=item B<--debug>
+
+Dump the downloaded web pages to stdout for debugging your F<watch> file.
+
+=item B<--check-dirname-level> I<N>
+
+See the below section L<Directory name checking> for an explanation of this option.
+
+=item B<--check-dirname-regex> I<regex>
+
+See the below section L<Directory name checking> for an explanation of this option.
+
+=item B<--user-agent>, B<--useragent>
+
+Override the default user agent header.
+
+=item B<--no-conf>, B<--noconf>
+
+Do not read any configuration files. This can only be used as the first option
+given on the command-line.
+
+=item B<--help>
+
+Give brief usage information.
+
+=item B<--version>
+
+Display version information.
+
+=back
+
+B<uscan> also accepts following options and passes them to B<mk-origtargz>:
+
+=over
+
+=item B<--symlink>
+
+Make B<orig.tar.gz> (with the appropriate extension) symlink to the downloaded
+files. (This is the default behavior.)
+
+=item B<---copy>
+
+Instead of symlinking as described above, copy the downloaded files.
+
+=item B<---rename>
+
+Instead of symlinking as described above, rename the downloaded files.
+
+=item B<---repack>
+
+After having downloaded an lzma tar, xz tar, bzip tar or zip archive, repack it
+to a gzip tar archive, if required. The unzip package must be installed in
+order to repack .zip archives, the xz-utils package must be installed to repack
+lzma or xz tar archives.
+
+=item B<--compression> [ B<gzip> | B<bzip2> | B<lzma> | B<xz> ]
+
+In the case where the upstream sources are repacked (either because B<--repack>
+option is given or F<debian/copyright> contains the field B<Files-Excluded>), it is
+possible to control the compression method via the parameter (defaults to
+B<gzip>).
+
+=item B<--copyright-file> I<copyright-file>
+
+Exclude files mentioned in B<Files-Excluded> in the given I<copyright-file>.
+This is useful when running B<uscan> not within a source package directory.
+
+=back
+
+=head1 CONFIGURATION VARIABLES
+
+For the basic usage, B<uscan> does not require to set these configuration
+variables.
+
+The two configuration files F</etc/devscripts.conf> and F<~/.devscripts> are
+sourced by a shell in that order to set configuration variables. These
+may be overridden by command line options. Environment variable settings are
+ignored for this purpose. If the first command line option given is
+B<--noconf>, then these files will not be read. The currently recognized
+variables are:
+
+=over
+
+=item B<USCAN_DOWNLOAD>
+
+If this is set to B<no>, then newer upstream files will not be downloaded; this
+is equivalent to the B<--report> or B<--no-download> options.
+
+=item B<USCAN_PASV>
+
+If this is set to yes or no, this will force FTP connections to use PASV mode
+or not to, respectively. If this is set to default, then B<Net::FTP(3)> makes
+the choice (primarily based on the B<FTP_PASSIVE> environment variable).
+
+=item B<USCAN_TIMEOUT>
+
+If set to a number I<N>, then set the timeout to I<N> seconds. This is
+equivalent to the B<--timeout> option.
+
+=item B<USCAN_SYMLINK>
+
+If this is set to no, then a I<pkg>_I<version>B<.orig.tar.{gz|bz2|lzma|xz}>
+symlink will not be made (equivalent to the B<--no-symlink> option). If it is
+set to B<yes> or B<symlink>, then the symlinks will be made. If it is set to
+rename, then the files are renamed (equivalent to the B<--rename> option).
+
+=item B<USCAN_DEHS_OUTPUT>
+
+If this is set to B<yes>, then DEHS-style output will be used. This is
+equivalent to the B<--dehs> option.
+
+=item B<USCAN_VERBOSE>
+
+If this is set to B<yes>, then verbose output will be given. This is
+equivalent to the B<--verbose> option.
+
+=item B<USCAN_USER_AGENT>
+
+If set, the specified user agent string will be used in place of the default.
+This is equivalent to the B<--user-agent> option.
+
+=item B<USCAN_DESTDIR>
+
+If set, the downloaded files will be placed in this directory. This is
+equivalent to the B<--destdir> option.
+
+=item B<USCAN_REPACK>
+
+If this is set to yes, then after having downloaded a bzip tar, lzma tar, xz
+tar, or zip archive, uscan will repack it to a gzip tar. This is equivalent to
+the B<--repack> option.
+
+=item B<USCAN_EXCLUSION>
+
+If this is set to no, files mentioned in the field B<Files-Excluded> of
+F<debian/copyright> will be ignored and no exclusion of files will be tried.
+This is equivalent to the B<--no-exclusion> option.
+
+=back
+
+=head1 EXIT STATUS
+
+The exit status gives some indication of whether a newer version was found or
+not; one is advised to read the output to determine exactly what happened and
+whether there were any warnings to be noted.
+
+=over
+
+=item B<0>
+
+Either B<--help> or B<--version> was used, or for some F<watch> file which was
+examined, a newer upstream version was located.
+
+=item B<1>
+
+No newer upstream versions were located for any of the F<watch> files examined.
+
+=back
+
+=head1 DETAILS
+
+=head2 Details of per-site options
+
+As explained cursorily in the above section L<TYPICAL EXECUTION>,
+B<uscan> reads the per-site option specified in B<opts="> I< ... > B<"> to
+customize its behavior.
+
+Multiple per-site options I<option1>, I<option2>, I<option3>, ... can be set
+as:
+
+B<opts=">I<option1>B<,> I<option2>B<,> I<option3>B<,> I< ... >B<">
+
+The double quotes are necessary if options contain any spaces.
+
+The mangling rules set by the per-site option behave as if a Perl command
+"I<$target_string> B<~=> I<rule>" is executed but there are some notable
+details.
+
+=over
+
+=item * multiple rules can be specified for a I<rule> by making a concatenated string of B<,> (comma) separated operations.
+
+=item * I<rule> may only use the B<s>, B<tr> and B<y> operations.
+
+=item * When the B<s> operation is used, only the B<g>, B<i> and B<x> flags are
+available and rule may not contain any expressions which have the potential to
+execute code (i.e. the B<(?{})> and B<(??{})> constructs are not supported).
+
+=item * If the B<s> operation is used, the replacement can contain back references
+to expressions within parenthesis in the matching regex, like
+B<s/-alpha(\d*)/.a$1/>. These back references must use the B<$1> syntax, as the
+B<\1> syntax is not supported.
+
+=item * each operation can not contain B<;> (semicolon) nor B<,> (comma).
+
+=back
+
+=head2 Directory name checking
+
+Similarly to several other scripts in the B<devscripts> package, B<uscan>
+explores the requested directory trees looking for F<debian/changelog> and
+F<debian/watch> files. As a safeguard against stray files causing potential
+problems, and in order to promote efficiency, it will examine the name of the
+parent directory once it finds the F<debian/changelog> file, and check that the
+directory name corresponds to the package name. It will only attempt to
+download newer versions of the package and then perform any requested action if
+the directory name matches the package name. Precisely how it does this is
+controlled by two configuration file variables
+B<DEVSCRIPTS_CHECK_DIRNAME_LEVEL> and B<DEVSCRIPTS_CHECK_DIRNAME_REGEX>, and
+their corresponding command-line options B<--check-dirname-level> and
+B<--check-dirname-regex>.
+
+B<DEVSCRIPTS_CHECK_DIRNAME_LEVEL> can take the following values:
+
+=over
+
+=item B<0>
+
+Never check the directory name.
+
+=item B<1>
+
+Only check the directory name if we have had to change directory in
+our search for F<debian/changelog>, that is, the directory containing
+F<debian/changelog> is not the directory from which B<uscan> was invoked. This
+is the default behavior.
+
+=item B<2>
+
+Always check the directory name.
+
+=back
+
+The directory name is checked by testing whether the current directory name (as
+determined by pwd(1)) matches the regex given by the configuration file
+option B<DEVSCRIPTS_CHECK_DIRNAME_REGEX> or by the command line option
+B<--check-dirname-regex> I<regex>. Here regex is a Perl regex (see
+perlre(3perl)), which will be anchored at the beginning and the end. If regex
+contains a B</>, then it must match the full directory path. If not, then
+it must match the full directory name. If regex contains the string I<package>,
+this will be replaced by the source package name, as determined from the
+F<debian/changelog>. The default value for the regex is: I<package>B<(-.+)?>, thus matching
+directory names such as I<package> and I<package>-I<version>.
+
+=head1 HISTORY AND UPGRADING
+
+This section briefly describes the backwards-incompatible F<watch> file features
+which have been added in each F<watch> file version, and the first version of the
+B<devscripts> package which understood them.
+
+=over
+
+=item Pre-version 2
+
+The F<watch> file syntax was significantly different in those days. Don't use it.
+If you are upgrading from a pre-version 2 F<watch> file, you are advised to read
+this manpage and to start from scratch.
+
+=item Version 2
+
+B<devscripts> version 2.6.90: The first incarnation of the current style of
+F<watch> files.
+
+=item Version 3
+
+B<devscripts> version 2.8.12: Introduced the following: correct handling of
+regex special characters in the path part, directory/path pattern matching,
+version number in several parts, version number mangling. Later versions
+have also introduced URL mangling.
+
+If you are upgrading from version 2, the key incompatibility is if you have
+multiple groups in the pattern part; whereas only the first one would be used
+in version 2, they will all be used in version 3. To avoid this behavior,
+change the non-version-number groups to be B<(?:> I< ...> B<)> instead of a
+plain B<(> I< ... > B<)> group.

-.TH USCAN 1 "Debian Utilities" "DEBIAN" \" -*- nroff -*-
-.SH NAME
-uscan \- scan/watch upstream sources for new releases of software
-.SH SYNOPSIS
-\fBuscan\fR [\fIoptions\fR] [\fIpath-to-debian-source-packages\fR ...]
-.SH DESCRIPTION
-\fBuscan\fR scans the given directories (or the current directory if
-none are specified) and all of their subdirectories for packages
-containing a control file \fIdebian/watch\fR. Parameters are then
-read from those control files and upstream ftp or http sites are
-inspected for newly available updates (as compared with the upstream
-version number retrieved from the \fIdebian/changelog\fR file in the
-same directory). The newest updates are retrieved (as determined by
-their version numbers) and if specified in the \fIwatch\fR file, a program
-may then be executed on the newly downloaded source.
-.PP
-The traditional \fIdebian/watch\fR files can still be used, but the
-current format offers both simpler and more flexible services. We do
-not describe the old format here; for their documentation, see the
-source code for \fRuscan\fR.
-
-.SH FORMAT of debian/watch files
-
-The following demonstrates the type of entries which can appear in a
-\fIdebian/watch\fR file. Obviously, not all of these would appear in
-one such file; usually, one would have one line for the current
-package.
-
-.PP
-.nf
-# format version number, currently 3; this line is compulsory!
-version=3
-
-# Line continuations are performed with \fB\e\fR
-
-# This is the format for an FTP site:

-
-# This can be used if you want to override the PASV setting
-# for a specific site
-# opts=pasv ftp://.../...
-
-# This is one format for an HTTP site, which is the same
-# as the FTP format. \fBuscan\fR starts by downloading the homepage,
-# obtained by removing the last component of the URL; in this case,
-# \fIhttp://www.cpan.org/modules/by-module/Text/\fR

-# For GitHub projects you can use the tags or releases page. Since the archive

- https://github.com/<user>/<project>/tags (?:.*?/)?v?(\ed[\ed.]*)\e.tar\e.gz

-
-# This is another way of handling site with funny version numbers,

-opts=dversionmangle=s/\e+dfsg\ed*$// \e
- http://some.site.org/some/path/foobar-(.+)\e.tar\e.gz
-
-# The filename is found by taking the last component of the URL and

-# filename, use filenamemangle. For example,
-# <A href="http://foo.bar.org/download/?path=&download=foo-0.1.1.tar.gz";>

-.fi
-.PP
-Comment lines may be introduced with a `\fB#\fR' character. Continuation
-lines may be indicated by terminating a line with a backslash
-character.
-.PP
-The first (non-comment) line of the file must begin `version=3'. This
-allows for future extensions without having to change the name of the
-file.
-.PP
-There are two possibilities for the syntax of an HTTP \fIwatch\fR file line,
-and only one for an FTP line. We begin with the common (and simpler)
-format. We describe the optional opts=... first field below, and
-ignore it in what follows.
-.PP
-The first field gives the full pattern of URLs being searched for. In
-the case of an FTP site, the directory listing for the requested
-directory will be requested and this will be scanned for files
-matching the basename (everything after the trailing `\fB/\fR'). In the
-case of an HTTP site, the URL obtained by stripping everything after
-the trailing slash will be downloaded and searched for hrefs (links of
-the form <a href=...>) to either the full URL pattern given, or to the
-absolute part (everything without the http://host.name/ part), or to
-the basename (just the part after the final `\fB/\fR'). Everything up to
-the final slash is taken as a verbatim URL, as long as there are no
-parentheses (`\fB(\fR' and '\fB)\fR') in this part of the URL: if it does, the
-directory name will be matched in the same way as the final component
-of the URL as described below. (Note that regex metacharacters such
-as `\fB+\fR' are regarded literally unless they are in a path component
-containing parentheses; see the Atlas-C++ example above. Also, the
-parentheses must match within each path component.)
-.PP
-The pattern (after the final slash) is a Perl regexp (see
-\fBperlre\fR(1) for details of these). You need to make the pattern
-so tight that it matches only the upstream software you are interested
-in and nothing else. Also, the pattern will be anchored at the
-beginning and at the end, so it must match the full filename. (Note
-that for HTTP URLs, the href may include the absolute path or full
-site and path and still be accepted.) The pattern must contain at
-least one Perl group as explained in the next paragraph.
-.PP
-Having got a list of `files' matching the pattern, their version
-numbers are extracted by treating the part matching the Perl regexp
-groups, demarcated by `\fB(...)\fR', joining them with `\fB.\fR' as a separator,
-and using the result as the version number of the file. The version
-number will then be mangled if required by the uversionmangle option
-described below. Finally, the file versions are then compared to find
-the one with the greatest version number, as determined by \fBdpkg
-\-\-compare-versions\fR. Note that if you need Perl groups which are
-not to be used in the version number, either use `\fB(?:...)\fR' or use the
-uversionmangle option to clean up the mess!
-.PP
-The current (upstream) version can be specified as the second
-parameter in the \fIwatch\fR file line. If this is \fIdebian\fR or absent,
-then the current Debian version (as determined by
-\fIdebian/changelog\fR) is used to determine the current upstream
-version. The current upstream version may also be specified by the
-command-line option \fB\-\-upstream-version\fR, which specifies the
-upstream version number of the currently installed package (i.e., the
-Debian version number without epoch and Debian revision). The
-upstream version number will then be mangled using the dversionmangle
-option if one is specified, as described below. If the newest version
-available is newer than the current version, then it is downloaded
-into the parent directory, unless the \fB\-\-report\fR or
-\fB\-\-report-status\fR option has been used. Once the file has been
-downloaded, then a symlink to the file is made from
-\fI<package>_<version>.orig.tar.{gz|bz2|lzma|xz}\fR as described by the help
-for the \fB\-\-symlink\fR option.
-.PP
-Finally, if a third parameter (an action) is given in the \fIwatch\fR file
-line, this is taken as the name of a command, and the command
-.nf
- \fIcommand \fB\-\-upstream-version\fI version filename\fR
-.fi
-is executed, using either the original file or the symlink name. A
-common such command would be \fBuupdate\fR(1). (Note that the calling
-syntax was slightly different when using \fIwatch\fR file without a
-`\fBversion=\fR...' line; there the command executed was `\fIcommand filename
-version\fR'.) If the command is \fBuupdate\fR, then the
-\fB\-\-no\-symlink\fR option is given to \fBuupdate\fR as a first
-option, since any requested symlinking will already be done by
-\fBuscan\fR.
-.PP
-The alternative version of the \fIwatch\fR file syntax for HTTP URLs is as
-follows. The first field is a homepage which should be downloaded and
-then searched for hrefs matching the pattern given in the second
-field. (Again, this pattern will be anchored at the beginning and the
-end, so it must match the whole href. If you want to match just the
-basename of the href, you can use a pattern like
-".*/name-(.+)\e.tar\e.gz" if you know that there is a full URL, or
-better still: "(?:.*/)?name-(.+)\e.tar\e.gz" if there may or may not
-be. Note the use of (?:...) to avoid making a backreference.) If any
-of the hrefs in the homepage which match the (anchored) pattern are
-relative URLs, they will be taken as being relative to the base URL of
-the homepage (i.e., with everything after the trailing slash removed),
-or relative to the base URL specified in the homepage itself with a
-<base href="..."> tag. The third and fourth fields are the version
-number and action fields as before.
-.SH "PER-SITE OPTIONS"
-A \fIwatch\fR file line may be prefixed with `\fBopts=\fIoptions\fR', where
-\fIoptions\fR is a comma-separated list of options. The whole
-\fIoptions\fR string may be enclosed in double quotes, which is
-necessary if \fIoptions\fR contains any spaces. The recognised
-options are as follows:
-.TP
-\fBactive\fR and \fBpassive\fR (or \fBpasv\fR)
-If used on an FTP line, these override the choice of whether to use
-PASV mode or not, and force the use of the specified mode for this
-site.
-.TP
-\fBuversionmangle=\fIrules\fR
-This is used to mangle the upstream version number as matched by the
-ftp://... or http:// rules as follows. First, the \fIrules\fR string
-is split into multiple rules at every `\fB;\fR'. Then the upstream version
-number is mangled by applying \fIrule\fR to the version, in a similar
-way to executing the Perl command:
-.nf
- $version =~ \fIrule\fR;
-.fi
-for each rule. Thus, suitable rules might be `\fBs/^/0./\fR' to prepend
-`\fB0.\fR' to the version number and `\fBs/_/./g\fR' to change underscores into
-periods. Note that the \fIrule\fR string may not contain commas;
-this should not be a problem.
-
-\fIrule\fR may only use the '\fBs\fR', '\fBtr\fR' and '\fBy\fR' operations. When the '\fBs\fR'
-operation is used, only the '\fBg\fR', '\fBi\fR' and '\fBx\fR' flags are available and
-\fIrule\fR may not contain any expressions which have the potential to
-execute code (i.e. the (?{}) and (??{}) constructs are not supported).
-
-If the '\fBs\fR' operation is used, the replacement can contain
-backreferences to expressions within parenthesis in the matching regexp,
-like `\fBs/-alpha(\ed*)/.a$1/\fR'. These backreferences must use the
-`\fB$1\fR' syntax, as the `\fB\e1\fR' syntax is not supported.
-.TP
-\fBdversionmangle=\fIrules\fR
-This is used to mangle the Debian version number of the currently
-installed package in the same way as the \fBuversionmangle\fR option.
-Thus, a suitable rule might be `\fBs/\e+dfsg\ed*$//\fR' to remove a
-`\fB+dfsg1\fR' suffix from the Debian version number, or to handle `\fB.pre6\fR'
-type version numbers. Again, the \fIrules\fR string may not contain
-commas; this should not be a problem.
-.TP
-\fBversionmangle=\fIrules\fR
-This is a syntactic shorthand for
-\fBuversionmangle=\fIrules\fB,dversionmangle=\fIrules\fR, applying the
-same rules to both the upstream and Debian version numbers.
-.TP
-\fBfilenamemangle=\fIrules\fR
-This is used to mangle the filename with which the downloaded file
-will be saved, and is parsed in the same way as the
-\fBuversionmangle\fR option. Examples of its use are given in the
-examples section above.
-.TP
-\fBdownloadurlmangle=\fIrules\fR
-This is used to mangle the URL to be used for the download. The URL
-is first computed based on the homepage downloaded and the pattern
-matched, then the version number is determined from this URL.
-Finally, any rules given by this option are applied before the actual
-download attempt is made. An example of its use is given in the
-examples section above.
-.TP
-\fBpgpsigurlmangle=\fIrules\fR
-If present, the supplied rules will be applied to the downloaded URL
-(after any downloadurlmangle rules, if present) to craft a new URL
-that will be used to fetch the detached OpenPGP signature file for the
-upstream tarball. Some common rules might be `\fBs/$/.asc/\fR' or
-`\fBs/$/.pgp/\fR' or `\fBs/$/.gpg/\fR'. This signature must be made
-by a key found in the keyring \fBdebian/upstream/signing-key.pgp\fR or
-the armored keyring \fBdebian/upstream/signing-key.asc\fR. If it is not
-valid, or not made by one of the listed keys, uscan will report an
-error.
-.TP
-\fBrepacksuffix=\fIsuffix\fR
-If the upstream sources are modified because \fIdebian/copyright\fR contains
-the \fBFiles-Excluded\fR field, \fIsuffix\fR will be appended to the upstream
-version of the repacked tar archive. Common suffixes might be \fB+dfsg1\fR to
-indicate the removal of files that are not DFSG-compliant or \fB+ds1\fR for
-other reasons such as removal of prebuilt files or large embedded code copies.
-.SH "Directory name checking"
-Similarly to several other scripts in the \fBdevscripts\fR package,
-\fBuscan\fR explores the requested directory trees looking for
-\fIdebian/changelog\fR and \fIdebian/watch\fR files. As a safeguard
-against stray files causing potential problems, and in order to
-promote efficiency, it will examine the name of the parent directory
-once it finds the \fIdebian/changelog\fR file, and check that the
-directory name corresponds to the package name. It will only attempt
-to download newer versions of the package and then perform any
-requested action if the directory name matches the package name.
-Precisely how it does this is controlled by two configuration file
-variables \fBDEVSCRIPTS_CHECK_DIRNAME_LEVEL\fR and
-\fBDEVSCRIPTS_CHECK_DIRNAME_REGEX\fR, and their corresponding command-line
-options \fB\-\-check-dirname-level\fR and
-\fB\-\-check-dirname-regex\fR.
-.PP
-\fBDEVSCRIPTS_CHECK_DIRNAME_LEVEL\fR can take the following values:
-.TP
-.B 0
-Never check the directory name.
-.TP
-.B 1
-Only check the directory name if we have had to change directory in
-our search for \fIdebian/changelog\fR, that is, the directory
-containing \fIdebian/changelog\fR is not the directory from which
-\fBuscan\fR was invoked. This is the default behaviour.
-.TP
-.B 2
-Always check the directory name.
-.PP
-The directory name is checked by testing whether the current directory
-name (as determined by \fBpwd\fR(1)) matches the regex given by the
-configuration file option \fBDEVSCRIPTS_CHECK_DIRNAME_REGEX\fR or by the
-command line option \fB\-\-check-dirname-regex\fR \fIregex\fR. Here
-\fIregex\fR is a Perl regex (see \fBperlre\fR(3perl)), which will be
-anchored at the beginning and the end. If \fIregex\fR contains a '/',
-then it must match the full directory path. If not, then it must
-match the full directory name. If \fIregex\fR contains the string
-\'PACKAGE', this will be replaced by the source package name, as
-determined from the \fIchangelog\fR. The default value for the regex is:
-\'PACKAGE(-.+)?', thus matching directory names such as PACKAGE and
-PACKAGE-version.
-.SH EXAMPLE
-This script will perform a fully automatic upstream update.
-
-.nf
-#!/bin/sh \-e
-# called with '\-\-upstream-version' <version> <file>
-uupdate "$@"
-package=`dpkg\-parsechangelog | sed \-n 's/^Source: //p'`
-cd ../$package-$2
-debuild
-.fi
-
-Note that we don't call \fBdupload\fR or \fBdput\fR automatically, as
-the maintainer should perform sanity checks on the software before
-uploading it to Debian.
-.SH OPTIONS
-.TP
-.B \-\-report\fP, \fB\-\-no\-download
-Only report about available newer versions but do not download anything.
-.TP
-.B \-\-report\-status
-Report on the status of all packages, even those which are up-to-date,
-but do not download anything.
-.TP
-.B \-\-download
-Report and download. (This is the default behaviour.)
-.TP
-.B \-\-destdir
-Path of directory to which to download. If the specified path is not
-absolute, it will be relative to one of the current directory or, if directory
-scanning is enabled, the package's source directory.
-.TP
-.B \-\-force-download
-Download upstream even if up to date (will not overwrite local files, however)
-.TP
-.B \-\-pasv
-Force PASV mode for FTP connections.
-.TP
-.B \-\-no\-pasv
-Do not use PASV mode for FTP connections.
-.TP
-\fB\-\-timeout\fR \fIN\fR
-Set timeout to N seconds (default 20 seconds).
-.TP
-.B \-\-no\-symlink
-Do not call \fBmk\-origtargz\fR.
-.P
-The following options are passed to \fBmk\-origtargz\fR:
-.RS
-.TP
-.B \-\-symlink
-Make \fIorig.tar.gz\fR (with the appropriate extension) symlinks to the
-downloaded files.
-(This is the default behaviour.)
-.TP
-.B \-\-copy
-Instead of symlinking as described above, copy the downloaded files.
-.TP
-.B \-\-rename
-Instead of symlinking as described above, rename the downloaded files.
-.TP
-.B \-\-repack
-After having downloaded an lzma tar, xz tar, bzip tar or zip archive,
-repack it to a gzip tar archive, if required.
-The \fBunzip\fR package must be installed in order to repack .zip archives, the
-\fBxz-utils\fR package must be installed to repack lzma or xz tar archives.
-.TP
-\fB\-\-compression\fR [ \fBgzip\fR | \fBbzip2\fR | \fBlzma\fR | \fBxz\fR ]
-In the case where the upstream sources are repacked (either because
-\fB\-\-repack\fR option is given or \fIdebian/copyright\fR contains the
-field \fBFiles-Excluded\fR), it is possible to control the compression
-method via the parameter (defaults to \fBgzip\fR).
-.TP
-.B \-\-copyright\-file \fIcopyright-file\fR
-Exclude files mentioned in \fBFiles-Excluded\fR in the given copyright file.
-This is useful when running uscan not within a source package directory.
-.RE
-.TP
-.B \-\-dehs
-Use an XML format for output, as required by the DEHS system.
-.TP
-.B \-\-no-dehs
-Use the traditional uscan output format. (This is the default behaviour.)
-.TP
-\fB\-\-package\fR \fIpackage\fR
-Specify the name of the package to check for rather than examining
-\fIdebian/changelog\fR; this requires the \fB\-\-upstream-version\fR
-(unless a version is specified in the \fIwatch\fR file)
-and \fB\-\-watchfile\fR options as well. Furthermore, no directory
-scanning will be done and nothing will be downloaded. This option is
-probably most useful in conjunction with the DEHS system (and
-\fB\-\-dehs\fR).
-.TP
-\fB\-\-upstream-version\fR \fIupstream-version\fR
-Specify the current upstream version rather than examine the \fIwatch\fR file
-or \fIchangelog\fR to determine it. This is ignored if a directory scan is
-being performed and more than one \fIwatch\fR file is found.
-.TP
-\fB\-\-watchfile\fR \fIwatchfile\fR
-Specify the \fIwatchfile\fR rather than perform a directory scan to
-determine it. If this option is used without \fB\-\-package\fR, then
-\fBuscan\fR must be called from within the Debian package source tree
-(so that \fIdebian/changelog\fR can be found simply by stepping up
-through the tree).
-.TP
-\fB\-\-download\-version\fR \fIversion\fR
-Specify the version which the upstream release must match in order to be
-considered, rather than using the release with the highest version.
-.TP
-\fB\-\-download\-current\-version\fR
-Download the currently packaged version
-.TP
-.B \-\-verbose
-Give verbose output.
-.TP
-.B \-\-no\-verbose
-Don't give verbose output. (This is the default behaviour.)
-.TP
-.B \-\-no\-exclusion
-Do not automatically exclude files mentioned in
-\fIdebian/copyright\fR field \fBFiles-Excluded\fR
-.TP
-.B \-\-debug
-Dump the downloaded web pages to stdout for debugging your watch file.
-.TP
-\fB\-\-check-dirname-level\fR \fIN\fR
-See the above section \fBDirectory name checking\fR for an explanation of
-this option.
-.TP
-\fB\-\-check-dirname-regex\fR \fIregex\fR
-See the above section \fBDirectory name checking\fR for an explanation of
-this option.
-.TP
-\fB\-\-user-agent\fR, \fB\-\-useragent\fR
-Override the default user agent header.
-.TP
-\fB\-\-no-conf\fR, \fB\-\-noconf\fR
-Do not read any configuration files. This can only be used as the
-first option given on the command-line.
-.TP
-.B \-\-help
-Give brief usage information.
-.TP
-.B \-\-version
-Display version information.
-.SH "CONFIGURATION VARIABLES"
-The two configuration files \fI/etc/devscripts.conf\fR and
-\fI~/.devscripts\fR are sourced by a shell in that order to set
-configuration variables. These may be overridden by command line
-options. Environment variable settings are ignored for this purpose.
-If the first command line option given is \fB\-\-noconf\fR, then these
-files will not be read. The currently recognised variables are:
-.TP
-.B USCAN_DOWNLOAD
-If this is set to \fIno\fR, then newer upstream files will not be
-downloaded; this is equivalent to the \fB\-\-report\fR or
-\fB\-\-no\-download\fR options.
-.TP
-.B USCAN_PASV
-If this is set to \fIyes\fR or \fIno\fR, this will force FTP
-connections to use PASV mode or not to, respectively. If this is set
-to \fIdefault\fR, then \fBNet::FTP\fR(3) makes the choice (primarily based on
-the \fBFTP_PASSIVE\fR environment variable).
-.TP
-.B USCAN_TIMEOUT
-If set to a number \fIN\fR, then set the timeout to \fIN\fR seconds.
-This is equivalent to the \fB\-\-timeout\fR option.
-.TP
-.B USCAN_SYMLINK
-If this is set to \fIno\fR, then a pkg_version.orig.tar.{gz|bz2|lzma|xz}
-symlink will not be made (equivalent to the \fB\-\-no\-symlink\fR
-option). If it is set to \fIyes\fR or \fIsymlink\fR, then the
-symlinks will be made. If it is set to \fIrename\fR, then the files
-are renamed (equivalent to the \fB\-\-rename\fR option).
-.TP
-.B USCAN_DEHS_OUTPUT
-If this is set to \fIyes\fR, then DEHS-style output will be used.
-This is equivalent to the \fB\-\-dehs\fR option.
-.TP
-.B USCAN_VERBOSE
-If this is set to \fIyes\fR, then verbose output will be given. This
-is equivalent to the \fB\-\-verbose\fR option.
-.TP
-.B USCAN_USER_AGENT
-If set, the specified user agent string will be used in place of the
-default. This is equivalent to the \fB\-\-user-agent\fR option.
-.TP
-.B USCAN_DESTDIR
-If set, the downloaded files will be placed in this directory. This is
-equivalent to the \fB\-\-destdir\fR option.
-.TP
-.B USCAN_REPACK
-If this is set to \fIyes\fR, then after having downloaded a bzip tar,
-lzma tar, xz tar, or zip archive, \fBuscan\fR will repack it to a gzip tar.
-This is equivalent to the \fB\-\-repack\fR option.
-.TP
-.B USCAN_EXCLUSION
-If this is set to \fIno\fR, files mentioned in the field \fBFiles-Excluded\fR
-of \fIdebian/copyright\fR will be ignored and no exclusion of files will be
-tried. This is equivalent to the \fB\-\-no-exclusion\fR option.
-.SH "EXIT STATUS"
-The exit status gives some indication of whether a newer version was
-found or not; one is advised to read the output to determine exactly
-what happened and whether there were any warnings to be noted.
-.TP
-0
-Either \fB\-\-help\fR or \fB\-\-version\fR was used, or for some
-\fIwatch\fR file which was examined, a newer upstream version was located.
-.TP
-1
-No newer upstream versions were located for any of the \fIwatch\fR files
-examined.
-.SH "HISTORY AND UPGRADING"
-This section briefly describes the backwards-incompatible \fIwatch\fR file
-features which have been added in each \fIwatch\fR file version, and the
-first version of the \fBdevscripts\fR package which understood them.
-.TP
-.I Pre-version 2
-The \fIwatch\fR file syntax was significantly different in those days. Don't
-use it. If you are upgrading from a pre-version 2 \fIwatch\fR file, you are
-advised to read this manpage and to start from scratch.
-.TP
-.I Version 2
-devscripts version 2.6.90: The first incarnation of the current style
-of \fIwatch\fR files.
-.TP
-.I Version 3
-devscripts version 2.8.12: Introduced the following: correct handling
-of regex special characters in the path part, directory/path pattern
-matching, version number in several parts, version number mangling.
-Later versions have also introduced URL mangling.
-
-If you are upgrading from version 2, the key incompatibility is if you
-have multiple groups in the pattern part; whereas only the first one
-would be used in version 2, they will all be used in version 3. To
-avoid this behaviour, change the non-version-number groups to be
-(?:...) instead of a plain (...) group.
-.SH "SEE ALSO"
-.BR dpkg (1),
-.BR mk\-origtargz (1),
-.BR perlre (1),
-.BR uupdate (1),
-.BR devscripts.conf (5)
