    Summary: Assemble multiple Regular Expressions into a single RE
    Regexp::Assemble takes an arbitrary number of regular expressions
    and assembles them into a single regular expression (or RE) that
    matches all that the individual REs match.
    As a result, instead of having a large list of expressions to loop
    over, a target string only needs to be tested against one expression.
    This is interesting when you have several thousand patterns to deal
    with. Serious effort is made to produce the smallest pattern possible.
    It is also possible to track the original patterns, so that you can
    determine which, among the source patterns that form the assembled
    pattern, was the one that caused the match to occur.
    You should realise that large numbers of alternations are processed
    in perl's regular expression engine in O(n) time, not O(1). If you
    are still having performance problems, you should look at using a
    trie. Note that Perl's own regular expression engine will implement
    trie optimisations in perl 5.10 (they are already available in
    perl 5.9.3 if you want to try them out). `Regexp::Assemble' will
    do the right thing when it knows it's running on a a trie'd perl.
    (At least in some version after this one).
    Some more examples of usage appear in the accompanying README. If
    that file isn't easy to access locally, you can find it on a web
    repository such as or
