nomarch

============================== F E A T U R E S ==============================

nomarch lists/extracts/tests `.arc' archives. (It also handles `.ark'
files, they're exactly the same.) This is a *very* outdated file
format which should never be used for anything new, but unfortunately,
you can still run into it every so often (especially if you mess about
with old CP/M stuff). So nomarch is handy as a way to deal with these
files.

============================ R E Q U I R E M E N T ==========================

nomarch tested and worked fine on the following configurations:

- IcarOS i386               (Kickstart 51.51, Workbench 40.0, AROS ABIv0)
- AROS One i386             (Kickstart 51.51, Workbench 40.0, AROS ABIv0)

================================= U S A G E =================================

nomarch [-hlptUv] [archive.arc] [match1 [match2 ... ]]

OPTIONS

-h  give terse usage help.

-l  list files in archive. If verbose listings are enabled, it shows
    the filename, compression method, compressed/uncompressed size,
	date/time, and CRC; but by default, it just shows the filename,
	uncompressed size, and date/time.

-p  extract to standard output, rather than to separate files.

-t  test files in archive (more precisely, check file CRCs).

-U  use uppercase filenames; more precisely,
    preserve original case from archive.

-v  give verbose output (when used with `-l').
	   
[archive.arc] - the archive to operate on.

[match1 [etc.]] - optionally  specify  which  archive members
                  to list/extract/test. Those which match any of these
                  filenames/wildcards are processed. Wildcard operators
                  supported are shell-like `*' and `?', but don't forget
                  to quote arguments which use these 
                  (e.g.  `nomarch foo.arc '*.bar'').

EXTRACTING MULTIPLE ARCHIVES

nomarch follows the `unzip'-like practice of working on only one archive
per run, with further `filenames' given on the command-line actually
specifying files to extract (or whatever). The easiest way to work on
multiple files with nomarch is simply to run it multiple times using for;
for example (bash):

for i in *.arc; do nomarch $i; done

The above would extract all archives in the current directory.

BUGS
The CRC used by the format is only 16-bit,
so `-t' is a less-than-perfect test.

One compression method, obsolete even by `.arc' standards :-),
isn't supported yet. This is partly because I've yet to find
a single file which uses it, despite testing an awful lot of files.

Subdirectories in Spark archives are extracted as the `.arc'-format
files they really are, which may not be terribly convenient.
