You have had a lot of good answers to this, but I'll pitch in with
mine. I have a script here
<http://www.brunningonline.net/simon/python/multirep.py> which will
allow you to do this and more. It allows you to make multiple
replacements at once (i.e. you could replace 'foo' with 'spam' *and*
'bar' with 'lard' on one pass), and to optionally replace only whole
words.

HTH.
