Subject: Version 1.1 of the bindlib package: a library for abstract syntax

with binder.

I am please to announce the release 1.1 of the bindlib library for
Caml-Light:

THE BINLIB PACKAGE
------------------

This is a library for the Caml-Light (and Caml-Special-Light) languages (and
Sml-nj soon ... may be) providing reasonable tools to write programs
manipulating data structures with binders (like lambda-terms or quantified
formulae). It is quite efficient and not too difficult to use (at least for
me).

I do not know of any available alternative to this package resulting
in a code as small, and as efficient (both in memory and speed) !
So give it a try !

The change from the version 1.0 are:
------------------------------------

- Correct a MAJOR BUG: when more than one variable is bound outside
of the current sequence of binding, then the version 1.0 does not
work at all. This bug has now been corrected.

- The library now raises the exception "Binlib_error" instead of
"Invalid_argument".

- The memory usage has been optimised to take in account binder
which binds a variable with no occurrence. In the benchmark this
is not visible, but other examples shows an improvement of a factor
greater than 2 !

- The library only works for terms with less than 32768 free
variables in each sub-term. An exception is raised if you
use too many variables.

- The library has now been tested on a bigger scale and should be
more reliable (I hope).
