Running

encode

$ ./encode [-vh] [-i input] [-o output]

The encode program encodes a file. You can specify the following command line arguments.

  • -h: Shows help and usage
  • -i infile: Input containing graph (default: stdin)
  • -o outfile: Output of computed path (default: stdout)
  • -v: Enable verbose printing.
