INTRODUCTION

Inline::SLang -- Write Perl subs in S-Lang.

Inline::SLang lets you write Perl subroutines in S-Lang. It dynamically 
translates the parameters and return values into native data types for 
both languages.

From the S-Lang library home page at http://www.s-lang.org/

S-Lang is a multi-platform programmer's library designed to allow a
developer to create robust multi-platform software. It provides
facilities required by interactive applications such as display/screen
management, keyboard input, keymaps, and so on. The most exciting
feature of the library is the slang interpreter that may be easily
embedded into a program to make it extensible. 

Example:

   use Inline SLang => <<'END';
   define JAxH(x) {
     () = printf( "Just Another %s Hacker", x );
   }
   END
   print JAxH('Inline'), "\n";

When run, this complete program prints:

   Just Another Inline Hacker

==============================================================================

INSTALLATION

This module probably requires Inline.pm version 0.42 or higher to be 
installed. In addition, you need S-Lang library v1.4.0 or greater installed;
however, the the development of this module is done mainly against 1.4.4 and
1.4.8, so there is little support for 1.4.3 and earlier (i.e. I am more
likely to drop support rather than try and fix/work around issues).

If you want to use the BIND_NS option then I suggest you upgrade to at 
least v1.4.3, and with v1.4.7 you gain extra functionality (the "All"
option).

Currently I assume that S-Lang has been compiled with support for
floating-point and complex numbers.

For the moment I am also making use of the Test::More module for testing.
I believe this is only a part of Perl since version 5.8.0, so you may need 
to download it from CPAN (http://search.cpan.org/).

To install Inline::SLang do this:

  $ perl Makefile.PL
  $ make
  $ make test
  $ make install

For configuration options, enter

  $ perl Makefile.PL -help

The main options of interest are -slangdir or -slanglib/inc to specify
the location of the library and its include file. The program looks in
/usr, /usr/local, and - if installed - the ots directory within the
CIAO directory structure (http:://cxc.harvard.edu/ciao/).

This has only been tested in UNIX (Linux and Solaris) environments.

Note that you have to 'make install' before you can run it successfully.
