[PATCH v4 1/5] git-remote-mediawiki: Introduction of Git::Mediawiki.pm

[benoit.person@ensimag.fr]

From: Benoit Person <benoit.person@ensimag.fr>

Currently, the mw-to-git project contains only a remote helper
(git-remote-mediawiki.perl). To inmprove the user experience while working
with mediawiki remotes, new tools, designed for such cases, should be
created. To achieve this goal, the project needs a way to share code between
several scripts (remote helper, commands, ... ).

A perl package offer the best way to handle such case:
Each script can select what should be imported in its namespace.
The package namespacing limits the use of side effects in the shared code.

An alternate solution is to concatenate a "toolset" file with each *.perl
when 'make'-ing the project. In that scheme, everything is imported in the
script's namespace. Plus, files should be renamed in order to chain to Git's
toplevel makefile.
