ruby1.9.3 1.9.3.0-1ubuntu1 (amd64 binary) in ubuntu quantal

 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.
 .
 Ruby uses two parallel versioning schemes: the `Ruby library compatibility
 version' (1.9.1 for this package), which is similar to a library SONAME, and
 the `Ruby version' (1.9.3 for this package). Ruby packages in Debian are
 named using the Ruby library compatibility version, which is sometimes
 confusing for users who do not follow Ruby development closely. This package
 depends on the ruby1.9.1 package, and provides compatibility symbolic links
 from 1.9.3 executables and manual pages to their 1.9.1 counterparts.
