SLgtk 0.5.14 released

[Michael Noble <mnoble space mit edu>]

Dear Gtk and S-Lang Enthusiasts,

Version 0.5.14 of SLgtk is now available at

	http://space.mit.edu/CXC/software/slang/modules/slgtk

The SLgtk package wraps the GIMP toolkit widget set (Gtk) for use in
S-Lang, and provides a simple and modular way of adding graphical
interfaces to applications without recoding them from scratch as GUIs.
SLgtk bundles scores of guilets, ranging in function from simple
buttons and screen drawing all the way to through plotting and imaging
of FITS files.

SLgtk also includes VWhere, an iterative, visual extension to the 
powerful S-Lang 'where' filtering command as described at

		http://arxiv.org/pdf/astro-ph/0412003

This release includes almost 20 enhancements, highlights of which are
given below.  In addition to raw source code, binary distributions
are provided for Solaris, Linux, and Mac OS/X, compiled against either
S-Lang1 or S-Lang2.

Regards,
Michael S. Noble
