[lug] Advice on writing a config file (probably XML)

Lex and YACC are really good for things like scripting, and like Mr 
Klein said, are probably overkill for a simple config file.

I had used XML in the past for a config type file, however it wasn't 
really just simple profiles.  The config file actually "described" the 
way the program should behave (it was a "wizard" type app, and each top 
level XML block described a single page).

I would suggest, if your configs are going to remain simple, go with 
something like:


Yes, this is the Micro$soft INI file format, but it's pretty simple to 
setup, understand, read and write.

My $0.02...
