@hackage ghc-prof-flamegraph0.2.0.0

This is a small tool to convert GHC time profiling reports into a format understandable by the FlameGraph (https://github.com/brendangregg/FlameGraph) tool.

To use, first convert a `.prof` file into the flame graph format using ghc-prof-flamegraph:

$ cat ~/src/packdeps/packdeps.prof | ghc-prof-flamegraph > packdeps.prof.folded

Then you can use the file to produce an svg image, using the flamegraph.pl script:

$ cat packdeps.prof.folded | ~/src/FlameGraph/flamegraph.pl > packdeps.prof.svg

You can also generate a flamegraph using the allocation measurements, using the --alloc flag, number of entries using --entries flag, number of bytes allocated using --bytes. In order to use --bytes or --ticks flag one have to run program with +RTS -P -RTS in order to get those measurements.
