=head1 DESCRIPTION
The B<openpkg build> tool provides automated recursive from-scratch
-installation and updating of existing RPM packages (B<openpkg build>).
-It writes a shell script to standard output that installs or upgrades
-software packages including all dependencies. Packages that are upgraded
-automatically trigger rebuilds of all packages that depend on the
-upgraded package ("reverse dependencies"). The dependency information is
-read from an index generated by B<openpkg index>.
+installation of packages and the updating and upgrading of installed
+packages.
+
+It generates a Bourne-Shell script on standard output (F<stdout>)
+that can be executed to perform the package installation or
+updating/upgrading procedure for all requested packages and their
+dependencies.
+
+Packages that are upgraded automatically trigger rebuilds of all
+packages that depend on the upgraded package ("reverse dependencies").
+The dependency information is read from an XML/RDF index generated by
+the companion tool B<openpkg index>.
+
+=head1 ARGUMENTS
Packages are selected by providing a list of name patterns. Each
-pattern is either a package name or a prefix followed by a '*'
-character. Additionally you can append a discrimination prefix separated
-by a comma that matches against the full name-version-revision
-string.

+ # update all packages to their latest version

+
+=head2 Upgrade
+
+The following examples shows a complete procedure for upgrading (major
+OpenPKG version change) the an instance under F</openpkg> to OpenPKG
+2.X:
+
+ # upgrade the bootstrap package
+ $ /openpkg/bin/openpkg rpm --rebuild \
+ ftp://ftp.openpkg.org/release/2.X/SRC/openpkg-2.X.0-2.X.0.src.rpm
+ $ /openpkg/bin/openpkg rpm -Uvh \
+ /openpkg/RPM/PKG/openpkg-2.X.0-2.X.0.*.rpm
+
+ # upgrade OpenPKG Tool Chain
+ # (includes latest "openpkg build" command!)
+ $ /openpkg/bin/openpkg rpm -e openpkg-tools
+ $ /openpkg/bin/openpkg build openpkg-tools | sh
+
+ # upgrade the whole OpenPKG instance, in correct dependency
+ # order and by keeping all chosen build-time options.
+ $ /openpkg/bin/openpkg build -ZaKB | sh
+
+=head2 Deinstallation
+
+The following example shows how to deinstall
+an entire OpenPKG intance under F</openpkg>:
+
+ # remove all packages and the instance itself
+ $ /openpkg/bin/openpkg rpm -e \
