The 'grinder' utility generates a WordNet database from
lexicographers' source files.  Manual pages are inclued which describe
the format of the database and the lexicographers' files, as well as
how to run the "grind" program.

The environment variable WNSEARCHDIR is used by the 'lexgrep' command.
It indicates part of the directory path in which the lexicographers'
files are installed.  'rawfiles' is appended onto WNSEARCHDIR to
generate a complete path name.  The default for WNSEARCHDIR is
"/usr/local/lib/wordnet", therefore the lexicographers' files should
be installed in "/usr/local/lib/wordnet/rawfiles".  If you install the
files elsewhere, you either should set WNSEARCHDIR to be the leading
component of the path name and make a subdirectory "rawfiles" for the
lexicographers' files, or you should edit the 'lexgrep' script to
indicate the correct location of the files.

See the man page "grind(1)" for details on setting the environment
variable SENSEFILES.

To compile the "grind" program, you must first build the WordNet
library (in the 'lib' directory), the the grinder (in the 'grind'
directory).  Makefiles are included in these directories, however they
are Sun specific, and will require editing on other platforms.
