What I want to do is take an arbitrary string and substitute one
string for arbitrary substrings.  For example, substitute an 's' or
any number of 's's with the letter 't'.  Using sed, I'd just do a
s/ss*/t/ or s/s+/t/ (I think).  I'm going to be substituting in arbitrary
text, though, so I don't have the luxury of marking my substitutions
with %'s.

Do you know of a way to do this?
