$ python -m profile --help
Usage: profile.py [-o output_file_path] [-s sort] scriptfile [arg] ...

Options:
   -h, --help            show this help message and exit
   -o OUTFILE, --outfile=OUTFILE
                         Save stats to <outfile>
   -s SORT, --sort=SORT  Sort order when printing to stdout, based on
                         pstats.Stats class

Additionally, you can run pstats on the outfile for an interactive viewer:

$ python -m pstats visualize.prof
