ruby-defaults: Ruby for Debian
------------------------------

The purpose of the ruby-defaults package is to provide binary packages (mostly
metapackages) that will install the currently supported Ruby interpreter.
Specifically:

- ruby          Depends on the default Ruby interpreter.

- ruby-dev      Depends on the development files for the default Ruby interpreter

- ruby-all-dev  Depends on the development files for all supported Ruby
                interpreters. This will usually be a single version (the
                default one), but during transitions in unstable multiple
                versions might be supported.

                If you are not building Ruby packages for Debian, you probably
                do not need it.

                When building Debian packages, it is OK to only build for the
                default version, and using just `ruby` (instead of hardcoding
                the current default) will do that in a future-proof way.

To programmatically list all the supported versions, install the `gem2deb`
package and run `dh_ruby --print-supported`. To determine which is the default
version, just dereference the /usr/bin/ruby symbolic link.
