Several Perl books, including _Mastering Regular Expressions_ and, if I
remember correctly, _Learning Perl_, use variants of this example. In
essence, yes, if you want to match one of several constant strings like
this, the match will happen faster with a series of static regexes than
ch like the $str[] array. Also,
it's usefully indented, because Readability Matters.

You should be able to apply that to each line of input to generate each

ng the whole thing in Perl, using a module
such as Mail::Simple. (There's at least a dozen others that could also
work, but anything with "::Simple" in the name is usually promising to

problem, as your wheel is unlikely to be any rounder than theirs are.
You'll be even gladder that you didn't have to write it from scratch.
