# This shell script will remove 'gomi' files.
#
# You can add your own "gomi" files in the rmfun section.
# The extensible and powerful feature is enabled by the use-specified "gomi" filename way.
# Previous approach you might adapt in removing 'gomi' files is to select carefully which file
# could be removed and even worry with prohibitive concentration about which couldn't,
# including important files like C source files you had much trouble to write up.
# It will cause disastrous predicament if you would mistakenly type 'rm -rf '.
# Also it may facilitate the choice of which file can be removed, you are only to type rmv!
# Note that you can even express pattern matching by '*', so the powerful expressive ability should readily exploited.
#

# Supported OSs are Linux (2.0.36), Solaris (5.6) and IRIX 6.5:
# versions are those I made certain to work well
# I suppose this is feasible on almost all platforms.
