/* XmdvTool V 1.0 - a program for multivariate data display using scatterplots,

** Matthew Ward, Computer Science Department, Worcester Polytechnic
** Institute, Worcester, MA 01609 USA (matt@cs.wpi.edu).  This program was
** built using Athena Widgets and the Widget Creation Library (see notes
** below), and as such, inherits the warranties of those packages, i.e.
** none.  Thanks to David E. Smyth and  Martin Brunecky for WCL - it really is
** a nice package!

/*
 * Version 2.0 - This version of the software introduces extensions
 *               related to the concept of brushing.  The user's manual
 *               contained in the distribution contains a full description
 *               of the extentions, but here is an overview:
 *
 *               - Simultaneous display of multiple brushes
 *               - New brush operations of quantitative display,
 *                 average, and masking.
 *               - Logical brush combinations
 *               - Ramped brush boundaries
 *               - Color Requester
 *               - Direct Manipulation of brushes
 *               - New methods of indirect manipulation through
 *                 brush tools and global resize tool
 *               - Prioritized brush operations
 *               - Data driven brushing

**
** Description:	This file contains main() for a Athena Resource Interpreter
**		which allows prototype interfaces to be built from
**		resource files.  The Widget Creation library is used.
**
** Notes:       This program uses the Xrm (X resource management) database
**              for widget tree definition and management.  This program
**              is dependent on the X Athena (Xaw) widget set, ALL the Xaw
**              widget classes are registered by the call to XpRegisterAll().
**
**              This version is slightly DIFFERENT than the original Mri
**              provided by David Smyth with Wcl 1.05. It uses the first
**              command line argument argv[1] as an application class, thus
**              directly selecting controlled user interface
