Subject: pkg versioning


rubyists-

is there a preferred method to accomplish this :

  require 'module_name', '1.0.1'

?

i am considering simply writing

  require_version 'module_name', '1.0.1'

where the version string is as a libtool/gnu version string denoting

  1.0.1 => interface, impl, age

    interface -> the interface number of the module
    impl      -> the implimentation number of this interface
    age       -> the difference between this, and the oldest interface
                 supported

these rules are spelled out very clearly in the libtool docs at
http://www.gnu.org/manual


the require_version method could then more properly be called 'ld' or 'link'

;-)

if some thought were given to this it could also work with C extensions.
