/* fsanot.c 3/11/94.
* calculates "not" of a finite state automaton
*
* SYNOPSIS:  fsanot [-ip d/s[dr]] [-op d/s] [-silent] [-v] [-l/-h] filename
* Input is from filename, which should contain a fsa.
* Output is to filename.not
*
* OPTIONS:
* -ip d/s[dr]  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)
