= Ruby Packaging Standard

The aim of this document is two-fold.  First, to specify a common
structure of how a Ruby package distributed as source (that is, but
not limited to, development directories, version-controlled
repositories, .tar.gz, Gems, ...) should conform to.

Second, to document common and proven ways to structure Ruby packages,
and to point out certain anti-patterns that sneaked into common use.
It is by intent not to innovate.
