- ----------------------------------------------------------
-
- This is the RE-distributed gzip executable, version 1.2.4,
- for Amiga. It is being redistributed due to a bug in the
- previous distribution (see below).
-
- Provided here is the "gzip" utility command only.
- (no "gunzip", "gzcat", or unix shell scripts included)
-
- The gzip command can be linked or duplicated on your system
- to produce the gzcat and gunzip commands, if desired.
- Otherwise, command line options passed to gzip can
- provide that functionality. For example, "gzip -d"
- is equivalent to "gunzip".
-
- ----------------------------------------------------------
-
- In conformance with the GNU license, source code is
- widely available for this product. The master repository
- is accessible via anonymous ftp at:
-
- prep.ai.mit.edu:/pub/gnu
-
- The gzip code will normally be named, "gzip-m.r.p.tar.Z",
- where the "m.r.p" indicates the current released "major",
- "revision", and "patch" level number.
-
- Also, see the README and COPYING files in this archive for
- more information.
-
- The BUG reporting procedure is outlined in the README file.

-
- BUG ALERT ! Previous distributions, called "gzip124x.lha"
- or "gzip124x.zip", compiled with SAS/C version 6.51, have
- a serious bug, seemingly caused by the compiler (but still
- uncertain at the date of this note). Although that version
- is able to properly decompress files without error, it creates
- corrupt archives when compresseing files. This is not detected
- until the archive is attempted to be decompressed. The error
- is manifested by a "CRC error" during decompression.
- NOTE: Sometimes, CRC errors are valid, meaning that the file
- was corrupted during transfer, but in THIS CASE, the gzip
- produced the corruption.
-
- Compiling with an earlier release of SAS/C, version 6.3,
- solved the problem. At the time of this release, I am
- attempting to track down and duplicated the compiler problem
- that caused this error, so I can report it to the SAS
- Institute. Currently, it is very difficult to isolate the
- problem because the code produced no enforcer hits, and
- executed properly. Only upon decompression does the
- error become observed.
-
- ----------------------------------------------------------
-
- The enclosed version of gzip does not work properly
- on Amigas running Workbench 1.3 (Kickstart less than 36).
- This is because of the lack of the ROM entrypoint, Examine_FH,
- used by the fstat() call in gzip.
-
- This will be corrected in a later version.
-
- For now, use standard output to pass files from gzip, as follows:
-
- (substitute your root filename in place of "filename" below)
-
- gzip >filename -dc filename.gz
-
- or
-
- gzip >filename.gz -c filename
