rp doc
Read the manual embedded in rp's own source comments.
rp doc is the reference surface: every user-facing command and verb carries
a documentation block in its source file, and this command renders it. Where
--help is a terse reminder of the flags, rp doc is the page you read to
learn a command — arguments, defaults, constraints, caveats, examples, and the
API call each verb makes. Library internals are never documented here.
