I could do it in lex, it would become much more readable, I suppose. It might have been done in awk or with sh+sed, but I'm not sure you could call it readable. :-) It is a 10 Kb C program (plus a 1 Kb shell script with two CAT <<EOF, one echo and a call to the C program), consisting basically of a big loop through a nineteen states state machine (switch). This program, as well as the script it replaces, is a preprocessor whose basic function is transforming <line> into "<line>\n", but with a few additional functions to annoy everyone's life (in particular, converting //-style comments into C-style comments, and quote-escaping). -- Daniel C.
