A number of public domain software products have been used in Eon/Eiffel.
They have been used in accordance with the authors wishes and with
appreciation for their work. All are available from internet archive
sites. 


1. The parser stage of Eon/Eiffel was produced with the Cocktail toolkit 
   developed by Dr. Josef Grosch. This is a lex/yacc replacement with extra 
   features. See the "cocktail.txt" file. This package can be found by 
   searching the internet for "cocktail".


2. The MSDOS Shareware version of Eon/Eiffel is produced with DJ Delorie's
   port of the Gnu C compiler. This can be obtained by searching the 
   internet for "djgpp".


3. The Linux Shareware version of Eon/Eiffel is produced with the Gnu
   C compiler. This can be obtained by searching the internet for "gcc".


4. Binary tree routines were written by Marcus J. Ranum and can be found
   by searching the internet for "b+tree". Since this is not as widely
   available as the above products, send email to eon@eonsw.demon.co.uk
   for more information.



Many thanks to Neil Wilson for his help in debugging the first versions.
