# add-modelines, a simple script to add comments to
# the beginning and end of source files for LibreOffice devs

# Blame goes to Jesse Adelman (at least at first)
# someone AT boldandbusted dotty-dot com

# (c) 2010 Bold and Busted LLC

# NOTE: At present, this script only works for files with C-like comments.
# NOTE: If you don't specify -p, the script will act on the current working directory.
# NOTE: If no arguments are specified, the definitions below are in effect.

# TO DO
#  - Deuglify?
#  - Make source file type agnostic modelines?
#  - Too many/too few comments?
#  - Handle top level source directories with whitespace names? (Do they exist?)

# Turn off globbing, helps with SourceFiles
