# Remove a feature that pops up a nag screen claiming the version is old
# after one year.  Just don't send in bug reports on an old version, OK folks?
# I hate to swim against upstream, but with all respect this feature is not
# helpful to distributions.

# Make xsublim (not included in the package but is in the 'hacks' directory)

( cd hacks
