+%   VERSION HISTORY:
+%      1.0  8/93
+%      1.2  10/93   major rewriting, only basic mode still
+%                   compatible with 1.0;
+%                   support for raw text list added
+%      1.3          fixed a minor bug of 1.2;
+%                   support for commenting out letters added
+%      2.0  11/93   compatible with 1.2, 1.3;
+%                   labels utility added; support for fixed number
+%                   of parameter lines added
+%      2.03 2/94    TAB char represents 8 spaces instead of 4;
+%                   fixed a bug on multi-columns output
+%      2.1  1/95    added parameter checker and dynamic array facilities;
+%                   compatible with LaTeX2e;
+%                   slight name changes: \figbox -->\textbox
+%      2.2  1/95    renamed an internal command (\array) to avoid
+%                   conflict with LaTex.
+%      2.3  5/2003  separated programmer's manual from the style file, 
+%                   added a new user manual.
+%
+%
