# Makefile Template v1.2
# Written by Milton Ngan (milton@comp.vuw.ac.nz)

#

# v1.2 Changes 
#
# Added in Lex source file support, will probably add Yacc at some stage as
# well :-)

# v1.1 Changes
#
# Updated .depend rule so that is creates a .depend for each source file
# this is more efficient. Also added HEADERS so that dependencies also depend
# on the header files. This is so that inter header dependecies will cause the
# appropriate dependency changes
