Purpose:
========
This tool allows you to reduce a data/ directory to just the latest page
revision of each non-deleted page (plus all attachments).

This is used to make the distributed underlay directory, but can also be
used for other purposes.

So we change like this:
    * data/pages/PageName/revisions/{1,2,3,4}
        -> data/pages/revisions/1  (with content of 4)
    * data/pages/PageName/current (pointing to e.g. 4)
        -> same (pointing to 1)
    * data/pages/PageName/edit-log and data/edit-log
        -> do not copy
    * data/pages/PageName/attachments/*
        -> just copy

Detailed Instructions:
======================
General syntax: moin [options] maint reducewiki [reducewiki-options]

[options] usually should be:
    --config-dir=/path/to/my/cfg/ --wiki-url=wiki.example.org/

[reducewiki-options] see below:
    0. To create a wiki data/ directory with just the latest revisions in the
       directory '/mywiki'
       moin ... maint reducewiki --target-dir=/mywiki
