#   GSRC = Grep SouRCe
#   
# Grep files, but only those in a project define by a TM5 rc file.
# 
# ARGUMENT : Regular Expression and options for Egrep
# --------
#
# OPTION
# ------
#
#     -r RCFILE : rc file (default is $RCFILE in settings, if defined, or the
#                          most recent)
#
#
# SETTING : specify your TM5 dir and default rc file in the SETTINGS
# --------- section 
#
#
# EXAMPLES 
# ---------
#
#    gsrc -in "module dep"
#    
#
# LIMITATIONS
# -----------
#  Works only with pycasso rcfiles.
#  A bit slow for repetitive search. See README in this dir for faster ways.
