What is ruby-standalone
ruby-standalone is:
Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in perl). It is simple, straight-forward, and extensible.
This package provides a Ruby interpreter without providing support for other Debian-provided Ruby packages, i.e. it won’t use any code from Debian packages that provide Ruby libraries, Rubygems won’t recognize libraries installed with Debian packages etc.
This package is mostly useful for server deployments or development environments where one wants or needs to obtain the Ruby interpreter from Debian (and thus benefit from having security updates, not having to build from source, obtaining pre-built binaries from a trusted source etc.), but install everything else from sources external to Debian such as rubygems.org.
