This is a command line application for analyzing MoarVM heap snapshots. First, obtain a heap snapshot file from something running on MoarVM. For example:
$ perl6 --profile=heap something.p6
Then run this application on the heap snapshot file it produces (the filename will be at the end of the program output).
zef install App::MoarVM::HeapAnalyzer
moar-ha heap-snapshot-1473849090.9
