README for guile-pcre
---------------------

guile-pcre is a set of language bindings to provide guile programs
with access to pcre (Perl-compatible regular expression library).

VERSION
-------

This is verion 1.0 of guile-pcre.

COMPATIBILITY
-------------

This verion of guile-pcre has been tested with guile 2.1 and pcre 8.32.

LIMITATIONS
-----------

No attempt has been made to support pcre external tables (locale
overrides), external patterns, reference counting, or the alternative
matcher.  As such there's no support for:

 - pcre_maketables
 - pcre_config flags PCRE_INFO_DEFAULT_TABLES, PCRE_INFO_FIRSTTABLE,
                     or PCRE_INFO_NAMETABLE.
 - pcre_pattern_to_host_byte_order
 - pcre_refcount
 - pcre_dfa_exec

Partial matching should be supported later.

API
---

The API is described in the guile-pcre.info file in the doc directory.
Or use "make html" and point your browser to
doc/guile-pcre.html/index.html.

LICENSE

Part of the motivation for this work was an apparent absense of
similar functionality elsewhere.  It looks like Rob Browning started
down this path is 2002 bug got bogged down in license incompatibility.

It still isn't clear that Rob Browning could have released what he had
done, but pcre is now listed in the FSF free software directory
http://directory.fsf.org/wiki/PCRE.  So it seems safe, now, to use
pcre from guile programs.

GPL Version 3 was selected because guile is licensed under LICENSE.
Since guile-pcre is fully dependent on guile, there seems no need for
an alternate license.

In the event that license incompatability becomes an issue, the author
