Hi Wim,
Let me know if you need perl help, ok?

Hi Taco,

I am doing regular expression (regex) and I am trying to process my 
Latex files (a lot)
to automate the translation to Context primitives.
I am partially  successfully but it is a complex job, so some of the 
Latex/Tex primitives
I convert by hand.

But thanks for your kind offer. Attached is my perl script, but don't expect
a lot from it or clean or optimized code, I wrote it in 2 hours.
Feel free to share it with anyone, if you think others may benefit.

Kind regards
Wim
