Bio::Root::Version - don't use, get version from each module
package Bio::Tools::NiftyFeature;
require Bio::Root::RootI;
# later, in client code:
package main;
use Bio::Tools::NiftyFeature 3.14;
## alternative usage: NiftyFeature defines own $VERSION:
package Bio::Tools::NiftyFeature;
my $VERSION = 9.8;
# later in client code:
package main;
# ensure we're using an up-to-date BioPerl distribution
use Bio::Perl 3.14;
# NiftyFeature has its own versioning scheme:
use Bio::Tools::NiftyFeature 9.8;
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.
