+Essentially like `folsomite`, but different. Different in the following ways:
 
 - More-general: consumers other than graphite can be defined
 - More-focused: only concerned with VM metrics, while `folsomite` ships off
   _everything_ from `folsom` (in addition to VM metrics)
-- Easier-to-reason-about implementation: well-defined metrics-to-binary
-  conversions, as opposed to the nearly-arbitrary term-to-string conversions
-  used in `folsomite`
