[Bioperl-l] Variation

[Stefan Kirov]

Heikki,
Well, actually I was thinking about contributing... I find Ensembl 
tremendously useful, but honestly the documentation is pretty bad. So 
bottom line making bioperl compliant access to ensembl should be quite 
useful. Can you let me know what the plans are (when there are some)? 
This way I will be able (probably) to help.
