28 June 1999:

I am pleased to annouce the long-overdue release
of Cost version 2.2.  Details at:

	<URL: http://www.flightlab.com/~joe/cost/index.html >

The software itself is at:

	<URL: ftp://ftp.crl.com:/users/je/jenglish/cost.tar.gz >

Cost is a structure-controlled SGML application programming tool.
It is implemented as a Tcl extension, and works in conjunction
with James Clark's nsgmls and/or sgmls parsers.  Cost is free software.

New in this release:

    + Should compile and install out-of-the-box on
      most Unix platforms, with any Tcl release from 7.5
      through 8.1.1 (courtesy autoconf).  I'm still working
      on Windows support...

    + Can load more than one document at a time, and switch
      between them with the new 'selectDocument' and 'withDocument'
      commands.  'setstream' and 'savestream' are provided as aliases
      so this release should be compatible with Boris Tobotras' patches.

    + Allows comments at certain places in specifications; this should
      also be compatible with Boris' version.

    + Preliminary support for XML (courtesy expat by James Clark).
      Note: XML support is largely untested and has a few
      known deficiencies (and probably several unknown one!)
      I'd appreciate any feedback/bug reports.

    + Released under a Tcl-style license instead of the "Artistic"
      license.  (This is closer to my idea of free software,
      and is several pages shorter.)

    + Cost can now be loaded as an extension into multiple Tcl
      interpreters without conflicts (it's still not thread-safe,
      however).

    + Many minor bugfixes, enhancements, and cleanups that
      have accumulated over the last three years; see the CHANGELOG
      for full details.
