Hello,
   AmigArc v0.23 is a version of ARC v5.0 ported to the Amiga. As such, it
can perform all of the normal ARC commands on '.ARC' files (for information
on ARC commands, find a copy of ARC.DOC).

Changes for version 0.23:
   1) Verbose ARChive listing now works with zero length files!

Changes for version 0.22:
   1) No noteworthy (none were reported!) bugs were fixed in this release
      and some of the code was cleaned up, and error reports now go to
      stderr instead of stdout.
   2) Control C is now supported (but could be better).
   3) This version was compiled using Lattice 3.10 which found some dormant
      bugs, and should be a little faster.
   4) File dates are now set when a file is extracted even when the current
      directory is not the target directory.

Known bugs remaining:
   1) The NOT operator for wild card matching does not always work. The fix
      looks to be a major rewrite of the WCmatch routines (sigh...).

Items of Note:
   1) The Run command will NOT be supported.

   2) The current version uses the MSdos '.ARC' file structure. This means
      that file names should follow MSdos conventions. The next version will
      be able to use the full AmigaDos filenames, and will have an MSdos
      compatibility option.

   3) Wild Cards are permitted in the filename portion of the template, but
      NOT in the path. The Wild Card scheme used is:

/*
 * WCmatch: Function to determine if the first string matches
 *    the template in the second string. If the third parameter
 *    is zero then case does NOT matter.
 *
 *    Returns:
 *       1 if string matches template.
 *       0 if string does NOT match template.
 *       Any other value indicates a template syntax error.
 *

 *
 *    Version 0.08
 *
 *    The following describes the syntax of a valid template.
 *       Items in braces ('{' and '}') may be repeated zero or more times.
 * 
 * <template>  := <AGroup>
 * 
 * <AGroup>    := <PGroup>{&<PGroup>}  'AND'
 *
 * <PGroup>    := <LGroup>{|<LGroup>}  'OR'
 *
 * <Group>     := <LGroup>{|<LGroup>}  'or'
 * 
 * <LGroup>    := <SGroup>{<SGroup>}   'Match-String'
 * 
 * <SGroup>    := (<Group>)            'grouping'
 *             := %                    'End-of-Name'
 *             := ^<SGroup>            'NOT'
 *             := <Literal1>
 *             := ?                    'Any-Character'
 *             := #<SGroup><MGroup>    'Zero-or-More Followed-By'
 *             := *<MGroup>            'Zero-or-More-of-Any-Character'
 *             := [<EnumList>]         'Enumeration-List'
 * 
 * <MGroup>    := <LGroup>
 *             :=
 *
 * <EnumList>  := <EnumPart>{,<EnumPart>}
 *
 * <EnumPart>  := <Literal2>
 *             := <Literal2>-<Literal2>   'All-Characters-From To'
 * 
 * <Literal1>  := <any printing character except:
 *                   '#', '%', '^', '&', '*', '(', ')', '|', '\', '[',
 *                   ']' and '?'>
 *             := \<any printing character including the above>
 * 
 * <Literal2>  := <any printing character except:
 *                   '\', '[', ']', '-' and ','>
 *             := \<any printing character including the above>
 *
 *
 *    NOTES:
 *       The 'AND' and the 'OR' functions have an implicit 'End-of-Name'
 *          function before their respective operators.
 *       The 'or' function moves the internal name pointer just past the
 *          first match that it finds.
 *       The second form of <EnumPart> matches the current name character
 *          if the first literal is less than or equal to the current name
 *          character, and the current name character is less than or equal
 *          to the second literal. Or if the first literal is less than the
 *          current name character, or the current name character is less
 *          than the second literal when the first literal is greater than
 *          the second literal. An <EnumPart> will never match the name
 *          terminator. e.g. 'a-f' will match 'a', 'b', 'c', 'd', 'e' and
 *          'f'; Whereas, 'f-a' will match all characters except 'a', 'b',
 *          'c', 'd', 'e' and 'f'.
 *       The '*' operator is equivalent to '#?'.

   4) If you experience a problem or bug in the program, please send
      a message describing what you were doing and what happened (be
      specific) at:

         Brand X Fido/SEAdog (141/255)
         (203) 255-7729

   5) Do NOT bother System Enhancement Associates about this program. They
      have little to do with the Amiga version of ARC.

   6) Suggestions, comments, criticisms, etc. are welcome and encouraged.

   7) This version of AmigArc does not have a "timeout" but please try to
      always use the latest version available.

   8) For the latest version of AmigArc check Brand X Fido or Amuse.

   9) To speed compression, ASSIGN ARCTEMP: RAM:

  10) The correct file size for AmigArc.022 is 50328 bytes.
