# Main targets:
# 	doc				- build class documentation
# 	dist			- build a distributable zip
# 	install			- install to user home latex path
#	uninstall		- uninstall/remove from user home latex path
# 	install-local	- install to local latex path 
# 						(may require elevated privileges)
# 	uninstall-local	- uninstall/remove from local latex path
# 						(may require elevated privileges)
#
# Other targets:
# 	sweep			- cleanup auxiliary generated files
# 	clean			- cleanup repo
#
# Variables:
# 	STRIP_CODE		- if "yes" strip docs from installed code
# 						(only for install and install-local targets)
# 	INSTALL_PATH	- install path
# 						(only for install target)
#
#
# Examples:
#
# 	$ INSTALL_PATH=./test STRIP_CODE=no make install
# 		install to "./test" and do not strip docs.
