Minor correction. TeX::Hyphen already does this, but it only works
with English hyphenation and standard "czech" substitution. I would
not trust it with any other language, which is why I'm working on
Text::Hyphen. Martin DeMello ported TeX::Hyphen from the Perl
version and it works incredibly well.

Text::Format can use TeX::Hyphen as a plugin, so formatting can
happen with hyphenation.

I am in the process of reworking the architecture of TeX::Hyphen
(the algorithm is not going to change; this simply WORKS!) and it
will better support a wide variety of languages. I have converted 16
of 42 TeX hyphenation files to the new Text::Hyphen format that will
be used for languages. After I finish Text::Hyphen (this weekend?) I
will be revisiting Text::Format. Because I am changing the
initialization API with no backwards compatibility, I will be
renaming Text::Format to Text::Formatter and bumping the version to
1.0. After this, I will be working on Ruwiki and Diff::LCS again,
but I will be open to new features for Text::Formatter.

The algorithm behind Text::Formatter is extgensive; I highly
recommend using this instead of trying to write your own.
