Build and.or process weighted finite state transducers (WFSTs) form
various input formats.  This program accepts descriptions
in the following formats and converts them to WFSTs
<itemizedlist>
<listitem><para>regular expressions</para></listitem>
<listitem><para>regular grammars</para></listitem>
<listitem><para>Koskenniemi/Kay/Kaplan context restriction rules</para></listitem>
</itemizedlist>
In addition various operations can be performed on two WFSTs
<itemizedlist>
<listitem><para>compose: form new WFST feeding output of first WFSTs into
second WFSTs.</para></listitem>
<listitem><para>union: form new WFST accepting the language both WFSTs
</para></listitem>
<listitem><para>intersect: form new WFST accepting only the language common
to both WFSTs
</para></listitem>
<listitem><para>concat: form new WFST accepting the language from the
concatenation of all strings in the first WFST to all strings in the
second.
</para></listitem>
</itemizedlist>
The newly formed WFSTs can be optionally determinized and minimzed.
The option asis allows a single WFSTs to be loaded and determinized
and/or minimized
