The profgraph library and executable should be make into a Ruby gem.
Ruby gems are the standard packaging mechanism for Ruby code. We should make a single gen (proftools?) to contain the library code we use for reading the SimpleProfiler output files, and also for the programs the user is expected to call directly (currently this is only profgraph).
The first version of this gem may be "installed" by downloading the git repository. We'll do the actual delivery as a gem, from a gem server, at some later date.
