/* fsamin.c 27/10/94.
* 25 / 1 / 00 added - s option .
* Minimises a finite state automaton
* Can either use stdin / stdout or files .
*
* SYNOPSIS : fsamin [ - ip d / s ] [ - op d / s ] [ - silent ] [ - v ] [ - s ] [ filename ]
*
* Input is from filename ( or stdin if not specified ) ,
* which should contain an fsa .
* Output is to filename . min , or stdout .
*
* OPTIONS :
* - ip d / s input in dense or sparse format - dense is default
* - op d / s output in dense or sparse format - default is as in current
* value of table - > printing_format , in the fsa .
* - v verbose
* - silent no diagnostics
* - l / - h large / huge hash - tables ( for big examples )
* - s print out the old state - new state correspondence
* to stdout after minimization .
