Pixilla did that for me (thanks Bradley) within
minutes of posting the new page.

== Introduction ==
In order to be a good 'Net citizen, it is
worthwhile to minimize the load on other's
servers. One simple technique is to specify
the `master_sites` parameter as specifically as
possible so that the other side does not have
to supply redirects in order to serve the file
we want. This how-to currently addresses only
SourceForge.
== SourceForge ==
Hopefully, the following example, using
mediainfo version 0.7.60, will illuminate the
process. The SourceForge home page for
mediainfo is
[[http://mediainfo.sourceforge.net]].
Initially, just specifying `'master_sites
sourceforge'` in the portfile under development
worked to retrieve the distfile. The log for
`'port fetch'` showed:
{{{
DEBUG: Executing org.macports.fetch (mediainfo)
--->
MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2
doesn't seem to exist in
/opt/local/var/macports/distfiles/mediainfo
---> Attempting to fetch
MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2
from http://iweb.dl.sourceforge.net/mediainfo
}}}
Use 'curl -IL
!http://iweb.dl.sourceforge.net/mediainfo/MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2'
to check for redirects. In this case the
output indicated redirects to a final address
of:
{{{
Location:
http://voxel.dl.sourceforge.net/project/mediainfo/binary/mediainfo/0.7.60/MediaInfo_CLI_0.7.60_GNU_FromSource.tar.bz2
}}}
To improve the `master_sites` parameter,
extract the bit:
`project/mediainfo/binary/mediainfo/0.7.60`
(and replace "0.7.60"--the version number in
this case--with ${version}). Thus
`'master_sites
sourceforge:project/mediainfo/binary/mediainfo/${version}'`.
Pat yourself on the back--you're done!
