1.0 (January 11, 1993):
	- Initial release.

1.1 (December 21, 1993):
	- Changed the WAIS headlines to the format:

		Filename FileType CoreFilename

	  where if the Filename is empty, then it uses the last component 
          of the CoreFilename as the Filename.

	- added support for new PostScript summarizer (pstext).

	- added support for new DVI summarizer (dvi2tty).

	- removed dvips binary from support dir (now uses dvi2tty)

	- now use wais-8-b5.1; still include patch file for wais-8-b5.

	- cleaned up the perl programs 'essence' and 'engine' to fix
	  minor bugs and make them easier to maintain.

	- added support for GNU zip compressed files.

	- added support for a stoplist to skip indexing some file
	  types; currently, Archive and Object files are not indexed; 
	  read from a configuration file (src/essence/stoplist).

	- added support for identifying file types by running an
	  external program; wrote identification programs and
	  summarizers for Bibliographic data and source code
	  distributions.

	- added a source code distribution summarizers that generates
	  a concise summary of a directory which contains a source code
	  distribution; uses first comments of C files and Makefiles,
	  manual page information, and README information; once a
	  directory has been identified as containing a source code
	  distribution, the file tree is pruned and none of its
	  decendants are indexed.

	- added support for pruning the file tree to index; currently,
	  whenever files with certain file types (eg.
	  SourceDistribution, you must edit the engine program to add
	  to these types) is indexed then any files/directories below
	  it are not indexed.

	- added support for writing summary files to subdirectories;
	  previously, the sums directory would get *very* large; now
	  engine creates subdirectories in the sums directory in which
	  to write the summary files.  Only 256 summary files are
	  permitted in each subdirectory; new subdirectories are
	  created when this limit is reached.

	- added support for essence to get the files to index from a 
 	  file rather than have to execute a find itself.  Note that 
	  if you use amd, then 'find /amd_mount_point -print' won't 
	  descend into the directory; the -depth flag has no effect.

	- added support for users to add their own keywords to summary
	  files during the essence build;  the -i flag causes essence
	  to stop before it calls waisindex to index the summary files;
	  at this time users can look the the sums/Map file to
	  determine which summary files they want to add keywords to.
	  After the user is finished adding keywords to the summary
	  files, engine will resume and finish the indexing.

	- added support for a quick reference "original file to type
	  and summary file mapping" file (datadir/sums/Map); users can
	  use this file to help them determine which summary files need
	  user-provided keywords (eg. all of the Image and Audio
	  summary files probably do).

	- improved engine performance by saving an exec when a
	  summarizer only uses the filename as its selected keywords.
	  Any file type that doesn't have a .sum program uses this method.

	- improved nested level performance by adding support to
	  recognize common nested levels and unraveling them in one
	  step; for example, tar.Z files are now unraveled in one step
	  rather than two.

	- improved engine performance in many minor ways.

	- minor improvements in many of the summarizers, including using
	  the skim program in the Text file summarizer (first 100 lines 
	  plus the first sentence of every remaining paragraph).

	- made filename.cf case sensitive (.Z vs .z)

	- better support for extracting Shell Archives with 'unshar'
 	
	- added support the Font file type

	- places Map file in the datadir not datdir/sums; this prevents
	  the Map file from being indexed.

	- changed Archive.sum to only print table of contents

	- improved installation process

	- updated manual page

	- fixed other minor bugs

1.1 (continued) (December 23, 1993):
 
        - added untested patch file for freeWAIS (src/Essence-freeWAIS.patch)

        - added doc/FAQ.txt
