# Makefile for Zip, ZipCloak, ZipNote and ZipSplit for
# djgpp 2.x
#
# This simple modified version of makefile.dj2 adds bzip2 support
# to Zip for djgpp 2.x and was donated by Robert Riebisch.
#
# Given standard djgpp 2.x and bzip2 installations, this should create a
# version of Zip 3.0 with bzip2 support.  Additional information is in
# bzip2/install.txt.

# ------------- file packer --------
# Laszlo Molnar who wrote DJ Packer and Markus F. X. J. Oberhumer who wrote
# the compression library used by the DJ Packer have collaborated on the
# Ultimate Packer for eXecutables, which has recently been released.  Look
# for upx???d.zip at     http://upx.sourceforge.net
# As an alternative, look for "djp.exe", now two years old, in the archive
# mlp107[b,s].zip, found in the same location as csdpmi?[b,s].zip (see below).
# If you have got an executable packer in your PATH, you may reduce the
# size of the disk image of the zip*.exe's by uncommenting the lines
# containing $(DJP) below where the exe's are built.

# These stand alone executables require dpmi services to run.  When
# running in a DOS window under windows 3.1 or later, the dpmi server
# is automatically present.  Under DOS, if a dpmi server is not installed,
# by default the program will look for "cwsdpmi.exe." If found, it will
# be loaded for the duration of the program.
# cwsdpmi is a "free" dpmi server written by Charles W. Sandmann
# (sandman@clio.rice.edu).  It may be found, among other sites, on SimTel
# and its mirrors in the .../vendors/djgpp/v2misc directory.
