I also crossed my mind. I can think of one problem. The lex/yacc parser is not
very "robust". If the grammar is wrong the parser quits. I don't know what is
required for a ctags parser. If it should continue parsing to grab as many
idents as possible even in case of syntax errors, my parser has a problem.

And second, I already have the new rewritten GPL'ed parser running. The lxr
perl overhead is small (when the new db structure is implemented). Only
Lang/VHDL.pm should be added beside the parser which is 3 files (Makefile,
vhdl.lex and vhdl.yacc).

When I get bored I'll take a look at ctags.

Robin.
