NAME
    Regexp::Trie - builds trie-ized regexp

SYNOPSIS
      use Regexp::Trie;
      my $rt = Regexp::Trie->new;
      for (qw/foobar fooxar foozap fooza/){
        $rt->add($_);
      }
      print $rt->regexp, "\n" # (?-xism:foo(?:bar|xar|zap?))

DESCRIPTION
    This module is a faster but simpler version of Regexp::Assemble or
    Regexp::Optimizer. It builds a trie-ized regexp as above.

    This module is faster than Regexp::Assemble but you can only add
    literals. "a+b" is treated as "a\+b", not "more than one a's followed by
    b".

    I wrote this module because I needed something faster than
    Regexp::Assemble and Regexp::Optimizer. If you need more minute control,
    use those instead.

TIPS
    See t/dict2rx.pl to find how to convert a big dictionary into a single
    regexp that can be later loaded as:

      my $rx = do 'dict.rx';

  EXPORT
    None.
