# Makefile for gzip (GNU zip)    -*- Indented-Text -*-
# This Makefile is for SAS/C 6.2 on the Amiga
# Made by Carsten Steger ([e-mail])

# Some notes on gzip for the Amiga:
# Due to a broken implementation of readdir() in the SAS/C 6.2 library
# you should not use gzip -r on a directory in the RAM-Disk. To zip all
# files in a directory 'dir' in the RAM-Disk use something like
# gzip ram:dir/#? ram:dir/#?/#? ...
# where the number of '#?'s reflects the depth of the directory 'dir'.
#
# Alas, the program has it's full functionality only if you have
# Kickstart 2.0 or higher installed. This affects the expansion of
# wildcards and the preservation of file access times. You should use
# a shell that does wildcard expansion under Kickstart 1.3.
