the browser will interpret the corresponding portion of the output as a tag

What we test is that the "go tool pprof" shipped with each Go release works
with programs from that release.

2. Pprof is used inside Google for C++, Java, and Go programs.
Because it was developed for that broader context, it is overgeneralized
when used here for the specific use case of profiling standard Go programs.
However, we've left the abstractions intact in order to share updates
between our vendored copy and Google's internal one.
