MiniVend 2.03d - Perl 5.004 and session fixes

	* Now compatible with Perl 5.004.

	* Sessions now can be handled in more than one way. The
	  default is with the new directive DomainTail set to "yes".
	  This qualifies the session ID with the major domain instead
	  of the IP number (i.e. aol.com instead of 152.163.202.72).
	  This should prevent problems with AOL and other ISPs who
	  use multiple proxy servers.

	  If you set DomainTail to 'no' and the new directive
	  IpHead to 'yes', this will use the major two dot-quads
	  of the IP number instead.  This will work well for systems
	  that have HostNameLookups off (on either the secure or non-secure
	  server).

      To keep the old (unreliable for AOL) behavior, set DomainTail
      to 'no' in minivend.cfg.

    * Server should now be reliable on BSD. Uses the File::Counterfile
      module to keep server counts. The SafeSignals directive (minivend.cfg)
      can be set to 'no' if you wish to try this for other operating
      systems.

MiniVend 2.03c - Minor change to 2.03b to fix sessions

MiniVend 2.03b - Bug fixes
* Made ready to run with Perl 5.004 by fixing SafeUntrap (will
  find correct version, use Opcode.pm style if version greater
  than 5.00320) and a few warnings

* Added all patches from patch set A

* Added patch that allows accesses from multiple proxy servers
  (i.e. AOL) while retaining session for SSL

* Added Safe{'carts'} access method

* Added 'do_tag' routine that allows access to tags within
  perl user subroutines.  Called with:

  	$data = do_tag("data arbitrary field1 $key");

MiniVend 2.03 - User reconfiguration and internet-domain server,

* Re-configuring a catalog can now be done on an individual
  basis.  No more server re-starts for a user to change their
  configuration.

* MiniVend no longer requires DBM, though it is still best to use
  GDBM or DB_File if available. There is a file-based session
  storage message mechanism, and product databases can
  be stored in memory.  This is automatically selected if
  appropriate.

* Multi-server mechanism changed completely.  Only one
  server runs when in quiescent state -- it forks additional
  servers as necessary, up to a limit you decide.  This works
  around a memory leak in Safe.pm, the server can now run for
  months on end.

* Runs on just about any Unix operating system with
  no changes, providing Perl 5.002 is available.  This
  includes IRIX, which formerly would not run MiniVend.

* Perl subroutines can now be defined on three levels, and
  directly called from MiniVend pages. Two use the Safe.pm module
  for enforcing security, while an administrator-enabled GlobalSub
  routine can run external programs for complete control.

* mSQL support is now considered stable, and the databases
  can be updated by forms from within MiniVend.

* The link CGI program may now use TCP-based sockets, which
  allows the link CGI to be located on a different machine than
  the MiniVend server.  Be careful of security, though!

* Perl link programs are provided for systems without a C compiler.
  (Solaris still needs a C compiler for File::Lock, unless it is
  already installed on Perl.) Not production quality -- user
  help would be appreciated.

* Search sorting can be done right on the page from returned
  fields, and be sorted by field based on form options.

* The [if ...] conditionals are much improved.  Contained
  HTML can now be deferred until the last interpolation pass
  with the [post] [/post] tag pair.

* New mv_click and mv_check special variables set multiple
  form parameters with a single form button.

* Cookies are only sent once if enabled, preventing annoying
  multiple warnings if the user has them turned on.

* If the user is going through multiple proxy servers (as
  AOL users do), the session will be stable.

* If REMOTE_USER is present, the IP address will not be
  used for the session name, allowing the same user to connect
  to a saved session from any machine.

* Many other minor bug fixes, improvements, and changes.
