10 o Removed 'Big+Fast' compress code (FBITS) because of compress speedup
28 The following preprocessor symbols control the compilation of "compress.c":

65 The output of compress 4.0 is fully compatible with that of compress 3.0.
66 In other words, the output of compress 4.0 may be fed into uncompress 3.0 or
67 the output of compress 3.0 may be fed into uncompress 4.0.

105 To compile compress:
107 cc -O -DUSERMEM=usermem -o compress compress.c
139 After compilation, move "compress" to a standard executable location, such

148 Next, install the manual (compress.l).

151 ln compress.l uncompress.l
152 ln compress.l zcat.l
156 cp compress.l /usr/man/man1/compress.1
158 ln compress.1 uncompress.1
159 ln compress.1 zcat.1
173 In the compress 3.0 source recently posted to mod.sources, there is a
177 4.2BSD Vax Makefile for compress.
179 Here is the README file from the previous version of compress (2.0):
