This module provides Guile Scheme bindings to regex, Henry Spencer's
regular expression library, version alpha3.8 or similar.  It's
supposed to be compatible with the Guile 1.4 and 1.6 series.

A compiled copy of regex must be available before this package can be
installed.  It can be obtained from various sources:

a) on a BSD system, it's probably already installed.

b) the rxspencer package from http://arglist.com/regex/ can be compiled
and installed.

c) the original regex.shar can be obtained from
ftp://ftp.zoo.toronto.edu/pub/.  From this can be built libregex.a and
regex.h, which guilerxspencer will link statically if present in its
include/library paths and not shadowed by other files of the same
name.

Once that's done, guilerxspencer can be compiled with something like:

./configure --prefix=<see below>
make
make install

The prefix given to configure should probably match the prefix where
Guile was installed.  Otherwise Guile won't find the module's scm file
in its site directory without further configuration.  Examples of
prefix:

--prefix=/usr --> /usr/share/guile/site
--prefix=/usr/local --> /usr/local/share/guile/site

If it is necessary to use a different prefix, then the
--with-guile=<prefix> option should be used to specify the prefix
under which Guile was installed.  When using the module, Guile will
not find the library file regex/spencer.scm unless the regex directory
can be found in the %load-path.  %load-path can be modified or a
symlink can be made.  The location of the compiled module is
hard-coded in the installed spencer.scm file.

See INSTALL for generic configure information and USAGE for examples
and module documentation.
