Nothing more simply than to install BesThes.
 
         BesThes consists of five files:
 
         1) BESTHES.COM, 2) BESTHES.DIC, 3) BESTHES.CDF, 4) BESTHES.DOC
         and 5) INSTALL.DOC.
 
         The first three are the operative ones and must be together in
         the same subdirectory, whose path cannot include extensions
         within the names of the subdirectories, e.g.
 
         C:\WORDPROC.ENG\THESAURUS\BESTHES - wrong.
 
         C:\WORDPROC\THESAURUS\BESTHES - correct.
 
         IMPORTANT! Don't change the names of BesThes' files.
