+Parser.
+-------
+
+The SL viewer code includes a flex/bison based parser that generates C++
+code that depends on various other bits of LL source code.  It's GPL 2,
+though the flex and bison source files includes no license text.
+
+Flex is BSD and written in C.  Bison is GNU (GPL 3 since 2.4.1, 2.3 is
+GPL2) and written in C.  It used to include info that stuff generated by
+bison had to be GPL.  Berkeley YACC is public domain, and written in C. 
+There is also btyacc, based on the berkeley version, but with some
+useful extras.  btyacc version 3 (the version coming from my version of
+Ubuntu) apparently no longer supports C, only C++.  It's written in C
+though.
+
+Let's see if flex and btyacc will do the trick, and output C.
+
+Might be best to have the LSL to Lua converter as a seperate executable.
