#   Be sure that CWEB version 3.0 or greater is installed before proceeding!
#   In fact, CWEB 3.61 is recommended for making hardcopy or PDF documentation.

#   If you prefer optimization to debugging, change -g to something like -O:
CFLAGS = -g

#   Uncomment the second line if you use pdftex to bypass .dvi files:
PDFTEX = dvipdfm
#PDFTEX = pdftex
