First, a word of caution: make a copy and edit that, in case something
goes wrong.

It should be pretty easy under Perl, depending on the complexity of the
edits you're trying to do.  Perl's regular expressions help quite a bit
in this sort of thing.

Before you begin, look at whether you want to read the whole file in as
a single scalar or do the editing line-by-line.  Some data files respond
better to one technique; some to the other...
