-# Makefile for gzip (GNU zip)    -*- Indented-Text -*-
-# This Makefile is for SAS/C 6.3 on the Amiga
-# Don't use it with SAS/C 6.2 or earlier versions. These versions will
-# produce incorrect code for trees.c because of a bug in the optimizer.
-# Made by Carsten Steger (carsten.steger@informatik.tu-muenchen.de)
-
-# Some notes on gzip for the Amiga:
-# Due to a strange implementation of the RAM-Disk on Commodore's part
-# 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.

-
-; Adapted for the Amiga by Carsten Steger <stegerc@informatik.tu-muenchen.de>
-; using the code in match.S.
-; The major change in this code consists of removing all unaligned
-; word accesses, because they cause 68000-based Amigas to crash.
-; For maximum speed, UNALIGNED_OK can be defined in Makefile.sasc.
-; The program will then only run on 68020-based Amigas, though.
-;
-; This code will run with registerized parameters too, unless SAS
-; changes parameter passing conventions between new releases of SAS/C.

-MAKEFILE.GCC	! Description for (vms-)make,  using gcc
-MAKEFILE.MMS	! Description for MMS-utility, using vaxc

-
-This file describe, how to compile and install the VMS-Port of gzip.
->>For restrictions or bugs due to the structure of the vms-file system
-refer to gzip.hlp.<<
-
-Installing gzip
-
-Since there are many makefiles there are many possibilities
-compiling and installing gzip. For most of them, it is important,
-that you start them from the SOURCE-Directory (that is where
-gzip.c is), not from the [.vms]-directory. Otherwise the compiler
-won't find the source-files.
-
-Using gcc saves disk-space, but needs longer to compile
-        VAXC	 gzip.exe 95/96 Blocks
-        gcc2.3.3 gzip.exe 86/87 Blocks
-
-To install gzip one has to perform the following steps:
-  1. compile sources (*.c, [.vms]*.c)
-  2. link executable gzip.exe
-  3. Make entries gunzip.exe and zcat.exe to gzip.exe.
-     These are similar to hardlinks in UNIX
-     >>If You wish to do this by hand, see for example makegzip.com.<<
-     The Entries can't be simply deleted, use  'set file /remove' .
-
-  4. Rename executables (*.exe) to Your prefered exe-directory. If it is on
-     another Device, then you should only copy gzip.exe and do the
-     entries gunzip.exe and zcat.exe by hand (3.).
-
-  5. Setting up Symbols for the executables:
-     Place the following lines in Your login.com
-     Change "disk:[directory]" as appropriate.
-        $ gzip   == "$disk:[directory]gzip.exe"
-        $ gunzip == "$disk:[directory]gunzip.exe"
-        $ zcat   == "$disk:[directory]zcat.exe"
-  6. insert help-file gzip.hlp in any Help-library,
-     for example in sys$help:helplib.
-     this can be done by $lib sys$help:helplib/help gzip
-     (I did not try this command)
-
-Steps (4.)5. through 6 must be done by hand.
-Steps 1 through 3(4.) may be done by one of the makefiles:
-
-a) MAKEGZIP.COM
-This was crated from MAKEFILE.VMS and later on edited. It uses the
-VAXC-Compiler and does compiling, linking and making the entries.
-Usage:
-- change to the Source-Directory
-- copy vms.c
-        $copy [.vms]vms.c []
-- start compiling, linking, entries
-        $@[.vms]makegzip
-if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
-continue at Step 4.
-
-b) MAKEFILE.VMS
-Makefile for a vms-make utility (NOT gnu-make).
-Is uses the VAXC-Compiler and has the Advantage over MAKEGZIP.COM
-that make checks dependencies. This is helpfull if You have to
-recompile several times, for example after editing the sources.
-- change to the Source-Directory
-- copy vms.c
-        $copy [.vms]vms.c []
-- start compiling, linking, entries
-        $make /input=[.vms]makefile.vms
-if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
-Continue at Step 4.
-
-c) MAKEFILE.GCC
-Same as MAKEFILE.VMS, but uses gcc
-- Use $make /input=[.vms]makefile.gcc   instead of make ....
-
-d) MAKEFILE.MMS
-Makefile for the MMS-utility. Similar to MAKEFILE.VMS
-- Use $mms /description=[.vms]makefile.mms  instead of make ....

-1 GZIP
-NAME
-     gzip, gunzip, zcat - compress or expand files
-
-SYNOPSIS
-     gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]
-     gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]
-     zcat [ -fhLV ] [ name ... ]
-
-2 DESCRIPTION
-     Gzip reduces the size of the named  files  using  Lempel-Ziv
-     coding  (LZ77).  Whenever possible, each file is replaced by
-     one with the extension .gz, while keeping the same ownership
-     modes,  access  and modification times.  (The default exten-
-     sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows  NT  FAT
-     and  Atari.) If no files are specified, or if a file name is
-     "-", the standard input is compressed to the  standard  out-
-     put.   Gzip will only attempt to compress regular files.
-
-     If the compressed file name is too long for its file system,
-     gzip truncates it.  Gzip attempts to truncate only the parts
-     of the file name longer than 3 characters.  (A part is  del-
-     imited  by  dots.) If the name consists of small parts only,
-     the longest parts are truncated. For example, if file  names
-     are  limited  to 14 characters, gzip.msdos.exe is compressed
-     to gzi.msd.exe.gz.  Names are not truncated on systems which
-     do not have a limit on file name length.
-
-     By default, gzip keeps the original file name and  timestamp
-     in  the  compressed  file. These are used when decompressing
-     the file with  the  -N  option.  This  is  useful  when  the
-     compressed  file  name  was truncated or when the time stamp
-     was not preserved after a file transfer.
-
-     Compressed files can be  restored  to  their  original  form
-     using  gzip -d or gunzip or zcat. If the original name saved
-     in the compressed file is not suitable for its file  system,
-     a  new  name is constructed from the original one to make it
-     legal.
-
-     gunzip takes a  list  of  files  on  its  command  line  and
-     replaces each file whose name ends with .gz, -gz, .z, -z, _z
-     or .Z and which begins with the correct magic number with an
-     uncompressed  file  without  the original extension.  gunzip
-     also recognizes the special  extensions  .tgz  and  .taz  as
-     shorthands   for  .tar.gz  and  .tar.Z  respectively.   When
-     compressing, gzip  uses  the  .tgz  extension  if  necessary
-     instead of truncating a file with a .tar extension.
-
-     gunzip can currently decompress files created by gzip,  zip,
-     compress,  compress  -H  or pack. The detection of the input
-     format is automatic.  When  using  the  first  two  formats,
-     gunzip  checks  a  32  bit  CRC. For pack, gunzip checks the
-     uncompressed length. The standard compress  format  was  not
-     designed  to  allow  consistency  checks.  However gunzip is
-     sometimes able to detect a bad .Z file. If you get an  error
-     when uncompressing a .Z file, do not assume that the .Z file
-     is correct simply because the standard uncompress  does  not
-     complain.  This generally means that the standard uncompress
-     does not check its input, and happily generates garbage out-
-     put.   The  SCO  compress -H format (lzh compression method)
-     does not include a CRC  but  also  allows  some  consistency
-     checks.
-
-     Files created by zip can be uncompressed  by  gzip  only  if
-     they  have  a  single member compressed with the 'deflation'
-     method. This feature is only intended to help conversion  of
-     tar.zip  files  to  the  tar.gz format. To extract zip files
-     with several members, use unzip instead of gunzip.
-
-     zcat is identical to gunzip -c. (On some systems,  zcat  may
-     be  installed  as  gzcat  to  preserve  the original link to
-     compress.) zcat uncompresses either a list of files  on  the
-     command   line   or   its  standard  input  and  writes  the
-     uncompressed data on standard output.  zcat will  uncompress
-     files that have the correct magic number whether they have a
-     .gz suffix or not.
-
-     Gzip uses the Lempel-Ziv algorithm used in  zip  and  PKZIP.
-     The  amount  of  compression obtained depends on the size of
-     the input and the distribution of common substrings.   Typi-
-     cally,  text  such  as  source code or English is reduced by
-     60-70%.  Compression is  generally  much  better  than  that
-     achieved  by  LZW  (as used in compress), Huffman coding (as
-     used in pack), or adaptive Huffman coding (compact).
-
-     Compression is always performed, even if the compressed file
-     is  slightly larger than the original. The worst case expan-
-     sion is a few bytes for the gzip file header, plus  5  bytes
-     every  32K  block, or an expansion ratio of 0.015% for large
-     files. Note that the  actual  number  of  used  disk  blocks
-     almost  never increases.  gzip preserves the mode, ownership
-     and timestamps of files when compressing or decompressing.
-
-2 OPTIONS
-     -a --ascii
-          Ascii text mode: convert end-of-lines using local  con-
-          ventions.  This  option  is supported only on some non-
-          Unix systems. For MSDOS, CR LF is converted to LF  when
-          compressing,   and  LF  is  converted  to  CR  LF  when
-          decompressing.
-
-     -c --stdout --to-stdout
-          Write output on standard output;  keep  original  files
-          unchanged.   If there are several input files, the out-
-          put consists of a sequence of independently  compressed
-          members.  To obtain better compression, concatenate all
-          input files before compressing them.
-
-     -d --decompress --uncompress
-          Decompress.
-
-     -f --force
-          Force compression or decompression even if the file has
-          multiple   links  or  the  corresponding  file  already
-          exists, or if the compressed data is read from or writ-
-          ten to a terminal. If the input data is not in a format
-          recognized by gzip, and if the option --stdout is  also
-          given,  copy the input data without change to the stan-
-          dard output: let zcat behave as cat. If -f is not given,
-          and when not running in the background, gzip prompts to
-          verify whether an existing file should be overwritten.
-
-     -h --help
-          Display a help screen and quit.
-
-     -l --list
-          For each compressed file, list the following fields:
-
-              compressed size: size of the compressed file
-              uncompressed size: size of the uncompressed file
-              ratio: compression ratio (0.0% if unknown)
-              uncompressed_name: name of the uncompressed file
-
-          The uncompressed size is given as -1 on VMS because
-          it is not possible to seek reliably to the end of the
-          compressed file, where this size is stored.
-
-          In combination with the --verbose option, the following
-          fields are also displayed:
-
-              method: compression method
-              crc: the 32-bit CRC of the uncompressed data
-              date & time: time stamp for the uncompressed file
-
-          The  compression  methods   currently   supported   are
-          deflate, compress, lzh (SCO compress -H) and pack.  The
-          crc is given  as  ffffffff  on VMS for the reason given
-          above about the uncompressed size.
-
-          With --name, the uncompressed name,  date and time  are
-          those stored within the compress file if present.
-
-          With --verbose, the size totals and  compression  ratio
-          for  all files is also displayed, unless some sizes are
-          unknown. With --quiet, the title and totals  lines  are
-          not displayed.
-
-     -L --license
-          Display the gzip license and quit.
-
-     -n --no-name
-          When compressing, do not save the  original  file  name
-          and time stamp by default. (The original name is always
-          saved  if  the  name  had  to   be   truncated.)   When
-          decompressing, do not restore the original file name if
-          present  (remove  only  the  gzip   suffix   from   the
-          compressed  file  name) and do not restore the original
-          time stamp if present  (copy  it  from  the  compressed
-          file). This option is the default when decompressing.
-
-     -N --name
-          When compressing, always save the  original  file  name
-          and  time  stamp; this is the default. When decompress-
-          ing, restore the original file name and time  stamp  if
-          present.  This option is useful on systems which have a
-          limit on file name length or when the  time  stamp  has
-          been lost after a file transfer.
-
-     -q --quiet
-          Suppress all warnings.
-
-     -r --recursive
-          Travel the directory structure recursively. If  any  of
-          the file names specified on the command line are direc-
-          tories,  gzip  will  descend  into  the  directory  and
-          compress  all  the  files it finds there (or decompress
-          them in the case of gunzip ).
-
-     -S suf --suffix suf
-          Use suffix suf instead  of  -gz.   Any  suffix  can  be
-          given,  but  suffixes  other  than -z and -gz should be
-          avoided to avoid confusion when files  are  transferred
-          to   other.   A  null  suffix  forces  gunzip  to   try
-          decompression on all given files regardless of  suffix,
-          as in:
-
-              gunzip --suffix "" *.*
-
-          Previous versions of gzip used the -z suffix. This  was
-          changed to avoid a conflict with pack on Unix.
-
-     -t --test
-          Test. Check the compressed file integrity.
-
-     -v --verbose
-          Verbose. Display the name and percentage reduction  for
-          each file compressed or decompressed.
-
-     -V --version
-          Version. Display the  version  number  and  compilation
-          options then quit.
-
-     -# --fast --best
-          Regulate the speed of compression using  the  specified
-          digit  #,  where  -1  or  --fast  indicates the fastest
-          compression method (less compression) and -9 or  --best
-          indicates the slowest compression method (best compres-
-          sion).  The default compression level is -6  (that  is,
-          biased towards high compression at expense of speed).
-
-2 ENVIRONMENT
-     The environment variable GZIP_OPT can hold a set of  default
-     options  for  gzip.  These options are interpreted first and
-     can be overwritten by explicit command line  parameters. For
-     example:
-           define GZIP_OPT "-8 -v"
-
-2 SEE ALSO
-     compress, zip, unzip
-
-2 DIAGNOSTICS
-     Exit status is normally 0; if an error occurs,  exit  status
-     is 1. If a warning occurs, exit status is 2.
-
-     Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...]
-             Invalid options were specified on the command line.
-     file: not in gzip format
-             The  file  specified  to   gunzip   has   not   been
-             compressed.
-     file: Corrupt input. Use zcat to recover some data.
-             The compressed file has been damaged. The data up to
-             the point of failure can be recovered using
-                   define /user sys$output file.recover
-                   zcat file
-     file: compressed with xx bits, can only handle yy bits
-             File was compressed (using LZW) by  a  program  that
-             could  deal  with more bits than the decompress code
-             on this machine.  Recompress  the  file  with  gzip,
-             which compresses better and uses less memory.
-     file: already has -gz suffix -- no change
-             The  file  is  assumed  to  be  already  compressed.
-             Rename the file and try again.
-     file already exists; do you wish to overwrite (y or n)?
-             Respond "y" if  you  want  the  output  file  to  be
-             replaced; "n" if not.
-     gunzip: corrupt input
-             A SIGSEGV violation was detected which usually means
-             that the input file has been corrupted.
-     xx.x%
-             Percentage  of  the  input  saved  by   compression.
-             (Relevant only for -v and -l.)
-     -- not a regular file or directory: ignored
-             When the input file is not a regular file or  direc-
-             tory, it is left unaltered.
-
-2 CAVEATS
-     On VMS:
-     - upper case options need quotes: gzip "-V".
-     - restoration of timestamps and version numbers is not supported
-     - If a compressed file already exists, gzip -f overwrites it, it
-       does not create a new version.
-     - multi-part gzip files are not supported.
-     - gunzip does not preserve the input file format. You can use a
-       separate utility to restore the original format.
-     - gunzip and zcat can be used only if you have created the
-       links to gzip as documented in makegzip.com.  Otherwise
-       you must use explicit parameters ("gzip -c" or "gzip -dc").
-     - gzip --list cannot give the uncompressed size and crc.
-
-     When writing compressed data to  a  tape,  it  is  generally
-     necessary  to pad the output with zeroes up to a block boun-
-     dary. When the data is read and the whole block is passed to
-     gunzip for decompression, gunzip detects that there is extra
-     trailing garbage after the compressed data and emits a warn-
-     ing  by  default.  You  have  to  use  the --quiet option to
-     suppress the warning. This option can be set in the GZIP_OPT
-     environment variable as in:
-         define GZIP_OPT "-q"
-
-2 BUGS
-     On VMS, files in VFC record format are not correctly handled by
-     the C runtime library (the linefeed character is suppressed).
-
-     In some rare cases, the --best option gives  worse  compres-
-     sion than the default compression level (-6). On some highly
-     redundant files, compress compresses better than gzip.
