Eli Compiler Construction System release

Version 4.1.0 of the Eli Compiler Construction System is now available
via anonymous ftp. Eli integrates off-the-shelf tools and libraries
with specialized language processors to generate complete textual
translators quickly and reliably. It simplifies the development of
new special-purpose languages, implementation of existing languages on
new hardware and extension of the constructs and features of existing
languages. More information is available for World-Wide Web users via
Eli's web pages:

Complete system documentation is also available in PostScript.


A paper outlining an early version of the system appeared in the
February, 1992 issue of "Communications of the ACM" (pages 121-131).

Version 4.1.0 contains numerous bug fixes and enhancements over
version 4.0.4. Users from prior versions are strongly encouraged to
view the "news" node in the on-line documentation or follow the
"what's new?" link from Eli's web pages to aid in migrating their
existing specifications to the new version. Version 4.1.0 integrates
an unparsing tool that simplifies copying the input to the output as
well as generating a human readable representation of the abstract
syntax tree. In addition, Eli's licensing has changed in this version.
Eli is now free software as defined by the GNU Public
License. Provisions are made to allow code generated by Eli to be used
without restriction (this is not true of the GNU obstack module, which
is contained in generated code and falls under the GNU Library
License).


We have tested Eli using the following operating systems:


      HP-UX version 9
      IRIX 5.3
      Linux 2.0.30
      OSF1 V4.0, V3.0
      SunOS 5.[45] (Solaris), 4.1.x


A more complete listing of operating system/compiler combinations can be
found in the top-level README of the distribution.


A mailing list devoted to discussions about Eli, announcements of bug
fixes, new features and releases and so on is available. If you would
like to be added to the eli mailing list, send a message with the body
"subscribe eli" to "majordomo@cs.colorado.edu". The address of the
list itself is "eli@cs.colorado.edu"; all mail of general interest to
the Eli community should be sent to this address. Error reports and
requests for help with specific problems should be sent to
"elibugs@cs.colorado.edu".


To obtain a copy of Eli over the network, either follow the "How can I
obtain a copy of Eli?" link from Eli's home page or use ftp to access
one of the following sites. If you use ftp, log on as "anonymous" and
give your net address when a password is requested. Then change to
the indicated directory and transfer the files you desire (remember
that compressed files, whose names end in ".gz", must be transferred
in binary mode):


      ftp.cs.colorado.edu, directory /pub/cs/distribs/eli
      ftp.uni-paderborn.de, directory /unix/eli
      ftp.cs.jcu.edu.au, directory /users/ASloane/eli


The Eli development team is best contacted via the mail alias
"elibugs@cs.colorado.edu". Because of our distribution around the
globe, mail to this alias is generally answered within a short time 24
hours per day. We can also be reached individually:
