-;; Revision 1.3 2010/06/11 11:01:46 jschrod
-;; New 2.4 ordrules supports regexps with start-anchored matches.
-;; Thus we can activate the leading blank processing rule. The
-;; parenthesis-discard rule must trigger everywhere, not just at the
-;; start of the index key.
-;; The blank suppression clause got optimized, it now triggers only
-;; if there are multiple blanks and not for each appearing blank.
-;;
-;; Revision 1.2 2005/05/09 20:21:11 jschrod
-;; Support handling of some common macros for logos; ignore all other
-;; TeX commands.
-;;
-;; Revision 1.1 2004/05/24 21:53:27 jschrod
-;; Standard modules, introduced in "LaTeX Companion Release".
