Merges multiple pprof profile files into one.

$ go get github.com/rakyll/pprof-merge

$ pprof-merge profile1.data profile2.data ...
$ pprof merged.data

Note: pprof already can work with multiple profile files. Example:

$ pprof profile1.data profile2.data ...

pprof-merge helps you to merge profiles in case you want to store them merged.
