+# makefile for PGP (unix)
+#
+# PGP 2.5 can be compiled to use either the modular exponentiation
+# routines that come with RSAREF 2.0 or those that are built into the
+# multiprecision library (mpilib) that comes with PGP.  For UNIX machines
+# (and probably VAX/VMS, too), we recommend using the RSAREF 2.0 routines.
+# For MSDOS, we recommend using the mpilib routines (there are assembly
+# language routines that mpilib can call under MSDOS making it much faster
+# than the C code in RSAREF 2.0).  To use the mpilib routines, you
+# should:
+#	(1) make sure you have the version of RSAREF 2.0 that comes with
+#	    the PGP 2.5 distribution,
+#	(2) in this makefile, add the compiler switch -DUSEMPILIB to
+#	    CFLAGS for your system below,
+#	(3) in the RSAREF 2.0 makefile, add the compiler switch
+#	    -DUSEMPILIB to CFLAGS before building RSAREF.
+# Note: when you build RSAREF with -DUSEMPILIB, rdemo and dhdemo will
+# fail to link, because they will be unable to find the modular
+# exponentiation routines.  This is OK.
+#
+# Alternatively, to build PGP 2.5 with the RSAREF exponentiation routines,
+#	(1) you can use any version of the March 16, 1994 distribution
+#	    of RSAREF 2.0,
+#	(2) you need not modify this makefile,
+#	(3) you need not modify the RSAREF 2.0 makefile.
+#
+#
+# CFLAGS options:
+#
+# -DHIGHFIRST if building PGP on a big-endian system
+# -DDEBUG     to include debugging information
+# -DNOTERMIO  if your system has no termios
+# -DSVR2      for System V release 2
+# -DDYN_ALLOC if your compiler does not support large static arrays
+# -DSMALL_MEM if your machine has a small memory (required for MSDOS)
+# -DIDEA32    if your int's are 32 bits this is probably faster
+#
+# -DPORTABLE  and
+# -DMPORTABLE to build the portable version of the RSA primitives
+#             (ie if no optimized asm versions are available)
+#
+# Define one of:
+# -DMERRITT    Merritt's modmult (fast on risc machines)
+# -DPEASANT    Russian peasant modulo multiply algorithm
+# -DUPTON      use Upton's modmult algorithm
+# -DSMITH      use Smith's modmult
+# See also the file platform.h for system defaults
+#
+# If you don't have a working FIONREAD ioctl you must use one of these:
+# -DUSE_SELECT to use select() system call
+# -DUSE_NBIO   to use non-blocking read()
