# Makefile for fast DES and UNIX password implementation
#
# entry points:
# too numerous to mention, and most of them are internal anyway; the
# more useful ones are:
#	make install
#		to make and then install everything
#	make lib
#		to make the library
#	make clean
#		to delete .o files
#	make clobber
#		to delete .o files, libraries, and executables

# LIBDIR	is where the library "libdes.a" goes
# INCDIR	is where the header file "des.h" goes
# DES, CRY, SHC	are the code numbers of the encryption and password
#		algorithms; the first two digits indicate the number
#		of bits passed to the combined spe function (06 and
#		12 are known; YOU MUST PUT THE ZERO BEFORE THE 6!)
#		and the third indicates the number of permutations
#		(1 or 3) to use to construct the key.
