Usage: $exe [options] input-file [output-file]
Options include:
-h, --help Show this message
-v Print the version
-f=format Set the output format, includes "default", "compressed"
-c Keep /* */ comments in output
-r Read from STDIN instead of input-file
-w Watch input-file, and compile to output-file if it is changed
-T Dump formatted parse tree
-X Dump raw parse tree
