+Conversion to Lua by Nikhil Helferty, 2011.
+Minor corrections by Bob Tennent rdt@cs.queensu.ca.
+
+NH: Comments marked NH (such as this one) are comments new to the Lua
+version. Most have to do with explaining any additions or changes made
+necessary due to differences between Lua and C. Comments not so marked
+are retained from C version.
+
+Almost all comments from the C version have been put in this version as
+well. Note that Lua variables are dynamically typed, and Lua has only
+one data structure called "tables" which, though more flexible than
+arrays, are essentially just used as arrays here.
+

+
+--[[
+
+ ChangeLog:
+
+ lua7 2011/04/21 RDT
+ Decode option argument for debugging.
+ Revert to accepting .mx1 or .tex filenames.
+ Rationalize file-name variables.
+
+ lua6 2011/04/18 RDT
+ Revert to stand-alone use.
+
+ lua5 2011/04/13 RDT
+ Allow .mx1 file to have a version number only.
+
+ lua4 2011/04/12 RDT
+ Adaptation to being called from musixtex.tex
