# This is a generic makefile for peps-2.0
# You may need to edit GSPATH or set it in
# your environment before running this makefile.
# Set it to wherever Ghostscript is on your system.
#
# Similarly, set GZPATH to wherever gzip is.
#
# If you do NOT want the gzip compression to be the
# CGI default, set GZIPIT = 0. If you want it to be
# the default, CGI or not, set GZIPIT = 1. If you
# want it to be the CGI default except for PNG
# output, set GZIPIT = 2.
#
# If you want PNM to be the default output format
# (as it was in peps-1.0), define PNMDEFAULT = 1
# (or any non-zero integer).
#
# I believe that HTTP_ACCEPT_ENCODING is used by
# all major web servers to inform CGI software what
# encoding a browser accepts. If your web server uses
# a different environment variable for this purpose,
# define HAE to it.
#
# If you want peps.mime somewhere ther than /etc,
# define ETC to a different path (with no trailing slash).
#
# The BINEXT variable is for cygwin users who should
# set it to .exe as in:
#	env BINEXT=.exe make install clean
#
#####################################################################
#
# The same source code is used for xpeps as for peps.
# Two additional variables are definied for xpeps and may
# need to be changed:
#
# XBINDIR tells us where to install the xpeps executable.
# XGRAY tells us what Ghostscript device to use for grayscale
# output. XCOLOR tells us what Ghostscript device to use
# for color output.
#
# EVAPORATIONDELAY is the default value for the -e switch
# of xpeps (has no meaning in peps). If used, the -e switch
# determines how long to keep the bitmap displayed on the screen
# (if not used, it is displayed until the user presses ENTER).
# The default value in the source code is (((unsigned)(-1))>>1),
# which is a rather large value (68 years on a 32-bit machine).
# If you redefine it here to a non-0 value, you will define
# the new delay in seconds.
