=== Development EXPGUI version ===

EXPGUI is not finished. It probably never will be, since there are so many features in GSAS that are not in EXPGUI and even more ways that use of GSAS can be made easier. There are actually two copies of EXPGUI at this site, [https://subversion.xray.aps.anl.gov/trac/EXPGUI/browser/trunk the standard distribution] and a copy that is used for  [https://subversion.xray.aps.anl.gov/trac/EXPGUI/browser/branches/sandbox development]. The latter changes, sometimes day-to-day, and on occasion may be broken, but may be of interest to folks who want to try out the latest additions as they are developed. (And you are welcomed to be involved in the development of new features, too.) You can have both copies of EXPGUI loaded on your computer, if you wish, see [wiki:AddSandbox these instructions].
