README for Jade autoconf support

With ./configure, you'll have an alternate method to prepare the source
distribution for building. This support is experimental, and I'd like
to receive feedback and patches for your operating system. If a build 
with autoconf doesn't work, you can always revert to the original Makefile
which is saved by configure to Makefile.dist. 'make mrproper' will undo
everything that has been modified by ./configure.

Please note that the autoconf support is not James', but my
responsibility: bother me with flames and patches, and I'll try tomake
sure that the next release gets fixed where necessary. James cannot do
more than forward everything to me, so please save his precious time.

Usage:
% ./configure; make; make install

configure options:

--help	
    Print a full list of options. This document only deals with the 
    non-standard options.
--enable-http
    This enables the built-in HTTP client so that you can use HTTP as
    a method for getting to system identifiers.
--enable-default-catalog=<pathlist>
    Provide the built-in definition for SGML_CATALOG_FILES.

Tested platforms:

    - SuSE Linux 5.3 (gcc 2.7.2.1, libc 5.5.46)
    - Solaris 2.6 (gcc 2.8.1)

Shared library support:

    By default, ./configure attempts to build shared libraries and link
    against them. This is done via the "libtool" utility, a utility that
    knows how to build shared libraries on a number of platforms.
    
    By default, only shared libraries are built. If you have difficulties
    building shared libraries, or you want to build static versions, you
    can use the --{enable,disable}{shared,static} options to configure
    libtool to your likings.

    According to the libtool 1.2 docs, shared libraries work on:

    One more note from the libtool documentation: the HP/UX sed seems
    to be badly broken, install GNU sed before attempting to build -
    libtool depends on a working sed.
