How to use with pprof

[SoftwareApe]

In the readme it says you can use this with pprof. We're using gperftools, and the output files can be rendered in various formats (e.g. traces) by using pprof. However I can't find documentation on

1. Which output format to use on pprof.
2. Which format to select for burn convert.

The examples seem to only concern perf.
