NAME

       ltsview - 3D interactive visualization of a labelled transition system

SYNOPSIS

       ltsview [OPTION]... [INFILE]

DESCRIPTION

       Start the LTSView application. If INFILE is supplied then the LTS in INFILE is loaded into the application.

       The  input  format  is  determined by the contents of INFILE. If that fails, an attempt is made to force the input format based on the file
       extension. The supported formats with file extensions are:
	 Aldebaran format (CADP; *.aut);
	 GraphViz format (*.dot);
	 Finite State Machine format (*.fsm);
	 mCRL SVC format (*.svc);
	 mCRL2 format (*.lts).

OPTIONS

       OPTION can be any of the following:

       --timings[=FILE]
	      append timing measurements to FILE. Measurements are written to standard error if no FILE is provided

       Standard options:

       -q, --quiet
	      do not display warning messages

       -v, --verbose
	      display short intermediate messages

       -d, --debug
	      display detailed intermediate messages

       --log-level=LEVEL
	      display intermediate messages up to and including level

       -h, --help
	      display help information

       --version
