# About gilCC - 
# Non intrusive C compiler Colorize shell works with any GCC version. An excellent option
# if you cannot upgrade your GCC compiler to version 4.9 but still want to add color
# to the output.
#
# Dependencies:
# This program depends on Ruby to work. Only tested with Ruby 2.0.0
#

# set the default command line for compiler
# for example:
# "gcc -g0 -d3 myfile.c" - you are calling gcc directly so your default command compiler is just 'gcc'
# "make arg1 arg2 arg3" - you are calling gcc via makefile so your default command compiler is just 'make'

# set the default command line here i.e. when you call gilCC without arguments it will

#	1. use cyan for gilCC messages and information to the user and Ruby code exceptions
#	2. white, green, yellow and red is reserved for the compiler output
