I have a package whose upstream distributes a tarball, always under
the same URL.  To get the version number out, I need to look in a
particular file in the tarball and find it there.  This is easy to do
with a fragment of shell code: use tar to extract the file to stdout,
pipe to something like awk to find and cut the version out.

My suggestion is that the mechanism here should allow an arbitrary
fragment of shell code to run on the retrieved file, printing the
found version to its stdout.

                                        --Barak.
