Other Alias

package Bio::Tools::NiftyFeature;, # later

DESCRIPTION

This module provides a mechanism by which all other BioPerl modules can share the same $VERSION, without manually synchronizing each file.

Bio::Root::RootI itself uses this module, so any module that directly (or indirectly) uses Bio::Root::RootI will get a global $VERSION variable set if it's not already.
