[dundee] Parser howto... possibly including bisons so watch out!

[Nistur]

Thanks for your advice, unfortunately the packages on the PS2 are 
somewhat limited and even though I could theoretically install such libs 
as xerces or something onto my playstation (although I may have a little 
difficulty finding ancient enough versions for compatibility, the system 
it's running is based on Red Hat 6 with a 2.2.1 kernel) I then have the 
problem it doesn't compile on the Uni PS2s.
If I'm writing my own config file layout I probably won't stick with XML 
as I'm not too keen on the look of it :P. From what I've seen of bison 
(and lex and yacc) it's not too complicated, just very cryptic. I'll 
have a look at the links in depth now and I have a PS2 lab in an hour's 
time, when I will probably look into the feasibility of writing my own 
parser and comparing it with bison.

Thanks for the help
