There were some modules that did not offer "or (at your option) any
later version" in their license and these had to be left alone.
This should solve the incorrect FSF address issue #4 on GitHub.
Recent GNU/Linux systems use ext3 or ext4 file systems. These use HTree
to index files. Wikipedia says: "HTree indexing improved the scalability
of Linux ext2 based filesystems from a practical limit of a few thousand
files, into the range of tens of millions of files per directory. [...]
HTree indexes are available in ext3 when the dir_index feature is
enabled. [...] HTree indexes are turned on by default in ext4."
Thus, instead of working on balanced-page-directories.pl, we decided to
get rid of these sub-directories altogether.
Unfortunately, this is backwards incompatible. Users wanting to upgrade
will need to install the upgrade.pl extension in order to upgrade the
file database.
Replaced the $Id$ tags in $WikiDescription for all the modules and wiki.pl itself with a link to the source and an appropriate wiki page, if possible. This is shown in action=version and should help users figure out what another wiki has installed.
