# preprocess.sh
#
# A simple code preprocessing wrapper that uses a combination of cpp, jssrip.py
# and sed to preprocess JavaScript files containing C-style preprocess macros
# (#include, #ifdef, etc.). Three options offer control over wether comments
# are preserved or stripped and whitespaces are compressed.
#
# Usage:
# preprocess.sh MODE SOURCE DEFINITIONS PREPRO_INCLUDE DESTINATION
#
# MODE:
#	commented		Preprocessed, still formated and commented
#	stripped		Preprocessed, formated but without comments
