createrepo enhancement update

An updated createrepo package that adds several enhancements is now
available.

The createrepo utility generates a common metadata repository from a
directory of RPM packages.

This updated package adds the following enhancements:

* a new "--update" option that updates existing metadata. This can result
in a performance increase.

* you can include a list of packages to create a new repository with using
the new "--pkglist" option. The "--pkglist" option takes a file name
containing a list of packages as an argument. For example, running the
'echo "test-1.0.0.rpm" > filelist' command, then the "createrepo
--pkglist=filelist" command, would create a new repository containing the
"test-1.0.0.rpm" RPM. As well, the "--pkglist" option can be used in
conjunction with the "--update" option to modify an existing repository.

* arbitrary metadata can be inserted into a repository using the new
"modifyrepo" command. For example, running the "modifyrepo test.xml
repodata/" command would compress and insert "test.xml" into the repository
as "repodata/test.xml.gz". The "repmod.xml" file will be updated to reflect
these changes.

All users of createrepo are advised to upgrade to this updated package,
which adds these enhancements.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
