makefile

reads a set of C-source files and generates a two-column listing of those sources

# Makefile for cdg - the C-source Documentation Generator

# Possible versions:
# -DPOSTSCRIPT	generates the PostScript version.
# -DLASERJET	generates the HP-LaserJet version.
# -DDESKJET	generates the HP-DeskJet 500 version.
# -DUSLETTER	generates a version for output on US Letter paper size
#		(only with PostScript printers - requires -DPOSTSCRIPT).
#		Default paper size is A4.

CFLAGS=-Wall -DPOSTSCRIPT
