### FIXME: This method breaks eggs.
# Unfortunately, instead of eggs being built by putting together package *.py
# files and data sanely at the last minute, they are built by putting them
# together in the build step.  This makes it extremely hard to put the
# separate pieces together in different places depending on what type of
# install we're doing.
#
# We can work around this by using package_data for static as eggs expect and
# then overriding install to install static in the correct place.
#
# Eventually someone needs to rewrite egg generation to tag files into
# separate groups (module, script, data, documentation, test) and put them
# into the final package format in the correct place.
#
# For some reason, the install-data switch also doesn't propogate to the build
# script.  So if we invoke install without --skip-build the app.cfg that is
# installed is also broken.  Grr....
