Some dockapps earlier versions of dockapps, e.g. the recently added wmacpi-ng,
may have different names than the directories they appear in. This patch adds
the ability to handle this situation by keeping track of the directory for
getting git information and skipping these dockapps when creating the "+date"
versions.
This script is run in the root directory of the dockapps repo to generate the
file used by the Window Maker website to store all of the information in the
dockapps section. Note that this file will then be submitted to the whome repo.
