obnam-viewprof — show Python profiler output
obnam-viewprof profile [sort-order]
obnam-viewprof shows a plain text version of Python profiler output. You can generate such output from Obnam by setting the OBNAM_PROFILE environment variable to a filename. The profile will be written to that filename, and you should give it to obnam-viewprof as an argument.
The sort-order argument defaults to cumulative and can be any of the orderings that the Python pstats library supports.
obnam-viewprof is mainly useful for those developing obnam(1).
