**
** Facility: UNZIP
**
** Module: VMS_UNZIP_CMDLINE
**
** Author: Hunter Goatley <goathunter@MadGoat.com>
**
** Date: 25 Apr 97 (orig. Zip version, 30 Jul 93)
**
** Abstract: Routines to handle a VMS CLI interface for UnZip. The CLI
** command line is parsed and a new argc/argv are built and
** returned to UnZip.
**
** Modified by:
**
** 02-013 S. Schweda, C. Spieler 29-Dec-2007 03:34
** Extended /RESTORE qualifier to support timestamp restoration
** options.
** 02-012 Steven Schweda 07-Jul-2006 19:04
** Added /TEXT=STMLF qualifier option.
** 02-011 Christian Spieler 21-Apr-2005 01:23
** Added /FULL=DIAGNOSTICS option modifier.
** 02-010 Steven Schweda 14-FEB-2005 20:04
** Added /DOT_VERSION (-Y) and /ODS2 (-2) qualifiers.
** 02-009 Steven Schweda 28-JAN-2005 16:16
** Added /TIMESTAMP (-T) qualifier.
** 02-008 Christian Spieler 08-DEC-2001 23:44
** Added support for /TRAVERSE_DIRS argument
** 02-007 Christian Spieler 24-SEP-2001 21:12
** Escape verbatim '%' chars in format strings; version unchanged.
** 02-007 Onno van der Linden 02-Jul-1998 19:07
** Modified to support GNU CC 2.8 on Alpha; version unchanged.
** 02-007 Johnny Lee 25-Jun-1998 07:38
** Fixed typo (superfluous ';'); no version num change.
** 02-007 Hunter Goatley 11-NOV-1997 10:38
** Fixed "zip" vs. "unzip" typo; no version num change.
** 02-007 Christian Spieler 14-SEP-1997 22:43
** Cosmetic mods to stay in sync with Zip; no version num change.
** 02-007 Christian Spieler 12-JUL-1997 02:05
** Revised argv vector construction for better handling of quoted
** arguments (e.g.: embedded white space); no version num change.
** 02-007 Christian Spieler 04-MAR-1997 22:25
** Made /CASE_INSENSITIVE common to UnZip and ZipInfo mode;
** added support for /PASSWORD="decryption_key" argument.
** 02-006 Christian Spieler 11-MAY-1996 22:40
** Added SFX version of VMSCLI_usage().
** 02-005 Patrick Ellis 09-MAY-1996 22:25
** Show UNIX style usage screen when UNIX style options are used.
** 02-004 Christian Spieler 06-FEB-1996 02:20
** Added /HELP qualifier.
** 02-003 Christian Spieler 23-DEC-1995 17:20
** Adapted to UnZip 5.2.
** 02-002 Hunter Goatley 16-JUL-1994 10:20
** Fixed some typos.
** 02-001 Cave Newt 14-JUL-1994 15:18
** Removed obsolete /EXTRACT option; fixed /*TEXT options;
** wrote VMSCLI usage() function
** 02-000 Hunter Goatley 12-JUL-1994 00:00
** Original UnZip version (v5.11).
** 01-000 Hunter Goatley 30-JUL-1993 07:54
** Original version (for Zip v1.9p1).
**
