Ben, thanks for the contribution. We did have a DoubleMetaphone
implementation available before the 1.1 release, but it was removed from
the repository because of licensing questions relating to the fact that
the code submitted was ported from a CPAN module covered under the Perl
Artistic License.
In this case, the file Dmetaph.cpp is Copyright 1998, 1999 Lawrence
Philips, and there I can find no mention of what terms this code falls
under. It may be wise to get the permission of the original author.
I'm interested in this as I found DoubleMetaphone to be a useful
algorithm.
Tim

I also wrote him a quick email, he gave me the same assurances. Submit
you code to Bugzilla, and I'll make sure the patch is applied posthaste.

Tim -
I have been in contact with Lawrence Philips who has
assured me that his code is in the public domain, and
is therefore completely available, eliminating any
legal difficulties related to the DoubleMetaphone
implementation.
Let me know if (and how) to proceed.
