Another interesting thing is that strings inside {} are left unsubstituted,
even internal pairs of {}'s are left alone. This is useful for outputting
chunks of Latex without having a zillion "leaning toothpicks" (escaping
all the {}\). If you do need to substitute the value of a variable etc you 
can use a dummy string and substitute afterwards with regsub eg
...
set header { ... yards of Latex here ... ##TITLE## ... }
regsub {##TITLE##} $header $titlestr header
puts $OUTFILE $header

Many thanks

I've kept clear of Python so far, is there anything in particular that
it's supposed to be especially good for, or is it just all down to taste?
