flite (speech synthesis engine)

Flite is a small, fast run-time synthesis engine, designed for
embedded systems and servers. Flite was developed by Alan W Black and
Kevin Lenzo at Carnegie Mellon University, in Pittsburgh.

Starting with version 2.0.0, flite is able to load extra voice files
at runtime, in its own .flitevox format. If you want to include
loadable voices in the package, download the ones you want from
http://festvox.org/flite/packed/flite-2.0/voices/ and place them
in the same directory as the SlackBuild. They will be installed in
/usr/share/flite/, and can be used with the flite's -voice option.

To skip building the HTML and GNU Info API documentation, set DOCS=no
in the environment. The man page will still be included. This option is
mainly provided in case a future version of texi2html has issues with
the texi2html options used by flite's doc/Makefile.
