What is it?

bioperl-dev is not a package as such, but a repository for new BioPerl code that is exploratory or experimental.

There is generally enough developer momentum behind the underlying concepts that, once the developer is satisfied with the state of the code, development will move to the Core or other distribution package.

On the other hand, if insurmountable difficulties ensue, or a better solution is found, a bioperl-dev module can die a quiet and dignified death.


bioperl-dev exists to provide space for projects with legs whose code (and particularly, whose API) is still unstable. The idea is to buffer the core and the other "production" packages against instability and unfinished and/or unmaintainable code. However, because bioperl-dev code is intentionally made available to larger BioPerl community through the usual outlets, it can benefit from (brave) user testing, bug reports, patches and dev mods in the same way the production packages do.

Lively and interesting discussions on bioperl-l have debated the pros and cons of the existence of bioperl-dev, compared to more determined branching and merging to trunk.

o Version

 This is bioperl-dev version 1.6.9, a developer release.

o Description 
 bioperl-dev contains experimental modules intended to expand the
 Bioperl envelope. New ideas for future point and stable releases
 are being explored here. Interested users are encouraged to 
 give these a try, keeping in mind the following points:

 o the modules here will likely depend on the current HEAD 
   revision of Bioperl (bioperl-live/trunk); a release version 
   may not suffice;

 o documentation is likely to be spotty at best;
 o the code should be considered unsupported, though a polite email
   to the dev is likely to elicit a positive response; 

 o the code should not be considered "production quality"; when this
   level is reached, bioperl-dev modules will graduate to the 
   core or the appropriate specialty package.

 See the Changes file for more information about what is contained in

o Installation

 See the accompanying INSTALL file for details on installing
