           Summary: Script to automatically generate package lists
          Severity: enhancement
    Classification: Unclassified
                OS: All
          Reporter: mtompset at hotmail.com
          Hardware: All
            Status: NEW
           Version: unspecified
         Component: contribs.koha-community.org
           Product: Koha

Inspired by the mess cleaned up by bug 8489, I proceeded to develop a script
that would:
- list packages not found in the default repository
- list packages found in the default repository
- list packages not found in the ubuntu.{version}.packages file list

Conversations with Robin Sheat gave me an useful grep expression to help with
the hunt when combined with apt-file. I was trying to do it a harder way, when
apt-file is perfect for this problem.

Conversations with Jared Camins-Esakov gave me the idea to expand the
functionality beyond just Ubuntu, as apt-file is capable of using a specific
sources.list file, rather than the default repositorys of one's OS.

The current help triggered on bad parameters reads something like:
===============================================================================
Usage: {path/to/}check_deps.sh [--koha-dir=<path>] [--list-dir=<path>]
                     [--dist=<dist>] [--release=<release>]
                     [--file=<file>] [--full=<full>]

koha-dir: The directory in which koha_perl_deps.pl is located.
          the default is `dirname "{path/to/}check_deps.sh"`.
list-dir: If you wish to use a specific source.list file
          you will need to specify the directory it is in.
    dist: This serves a dual role. Firstly, it is used to calculate
          the name of the source.list file, but also to determine
          which .packages file should be compared against in the
          install_misc directory under the koha directory.
          This should be specified along with the release parameter.
 release: This is the version number of the distribution of
          linux being used. It serves the same dual purpose.
          Sample valid values: 10.04, 12.04, 6.0.5
          The Debian value of 6.0.5 will be truncated to 6.0 solely.
          This should be specified along with the dist parameter.
    file: If you wish to keep the output around after running the
          script, give a file name to store it in. There will be
          three suffixes appended:
          1) .all - This is all the libraries it did find.
          2) .fix - These are the libraries missing from the
                    .packages file.
          3) .missing - This is lists libraries not found at all.
                        This means they should be added to the
                        koha-community repositories.
                        It's worthy of a bug report.
    full: Can be 0 or 1. For verbose output use 1. To just list
          missing files (0), that is the type 3 from above, are
          listed to STDOUT.

sample output line for found library:
   Net::Z3950::ZOOM ~ libnet-z3950-zoom-perl: /usr/lib/perl5/Net/Z3950/ZOOM.pm

sample output line for library that doesn't exist:
   {library name} NOT FOUND!

In the bizarre case that there is more than one possibility:
   GD ~: libgd-gd2-noxpm-perl: /usr/lib/perl5/GD.pm
   ~: libgd-gd2-perl: /usr/lib/perl5/GD.pm
GD is currently the only case, and so has a special exception.
If you find a new special case, please bug report it at
http://bugs.koha-community.org/bugzilla3

Sample uses: check_deps.sh | grep 'NOT FOUND'
             Find libraries which aren't in any repository.
             If you see {library name}, the parameters are wrong.

Sample uses: check_deps.sh | grep '~' | cut -f2- -d'~' | cut -f1 -d':'
             Find libraries which can be 'apt-get install'd
===============================================================================

Output of the script may need some tweaking. However, given that the three
files are generated, it could be completely ignored too. Though, I find I like
to read it just to be sure.

P.S. Try not to hurt my baby.
