  check_ltlspec - Performs LTL model checking
     _________________________________________________________________
   
   check_ltlspec [-h] [-m | -o output-file] [ltl-expression]
   
   Performs model checking of LTL formulas. If no ltl-expression is given
   at command line, then the previously parsed LTLSPEC, if any, are
   considered. LTL model checking is reduced to CTL model checking as
   described in the paper by [CGH97]
   
   Command options:
   
   -m
          Pipes the output generated by the command in processing
          LTLSPECs to the program specified by the PAGER shell variable
          if defined, else through the Unix "more" command.
          
   -o output-file
          Writes the output generated by the command in processing
          LTLSPECs to the file output-file.
          
   ltl-expression
          A LTL formula to be checked.
