COPYRIGHT INFORMATION

  The ocamlmerr program itself is public-domain software written by
Arthur O'Dwyer (that's me); feel free to use or modify it for whatever 
purpose.

  The files 'merr_parsing.ml' and 'merr_parsing.mli' are modifications
of files copyright and GNU LGPL Xavier Leroy, and I really don't know
how you're allowed to use them; see the OCaml copyright information,
I suppose.

  The rest of the files originate from course material at CMU (presumably
copyright Roland Flury and/or Peter Lee and/or CMU) and from my own course 
projects (released to the public domain by Arthur O'Dwyer); but then, I 
don't expect you to be using them for anything except perhaps to see what 
ocamlmerr does in a "real-world" (ha!) application.

README

  This directory will most likely not stick around very long.  The home of 
the ocamlmerr program is
http://www.contrib.andrew.cmu.edu/~ajo/free-software/ocamlmerr/
There is a description of the input format there, if you can't grok
the sample 'meta.err' in this directory by yourself.

  To build the sample compiler, download this whole directory onto your 
machine, tweak the paths in the Makefile, and say 'make'.  The build
process requires 'gcc', 'sed' (for a trivial search-and-replace operation
that can be done by hand if you're desperate), and of course the OCaml 
tools.  I will not troubleshoot the sample compiler, first because (as
noted above) it's not all mine and I don't want to encourage you to use
it; second because there are probably bugs in it anyway; and third because
I'm really tired of looking at this compiler; it's been almost a semester 
already!  I will, however, try to help anyone who wants to improve the
ocamlmerr tool itself.  Visit its home (URL above) first, though.

  The names "Merr" and "meta.err" and the whole basic idea of this program 
are due to Clinton Jeffery's original "Merr" for the Unicon programming 
language; that project's home page is
http://unicon.sourceforge.net/merr/

  Happy hacking!
