[Bioperl-l] SVN and ...Re: Perltidy

[Hilmar Lapp]

So should we set up a sandbox svn repository and those who would like  
to help out

- take shots at migrating bioperl (any current cvs snapshot will do)  
to svn

- you document what you find yourself having to do in trying to make  
it work

- you report back when you think you have a working repository

- we all get a defined amount of time to test to our hearts' content,  
say 2 weeks

- you fix issues that were encountered

- report back when done, followed by retesting for, say 1 week

- iterate previous 2 steps until no issues and no objections to  
migration

- two more weeks of warning period to all developers to commit all  
outstanding changes, or reapply them to a future svn checkout

- pull the trigger by locking down cvs, applying the migration as  
worked out before, and announcing that BioPerl is now on svn

- get free beer at next BOSC (I'll pay if no one else does)

This may not be precisely the plan that needs to be executed, but  
it's probably somewhere along those lines.

If there are volunteers who would like to spearhead this, then power  
to you - I think everyone is in favor and the advantages of svn don't  
need to be debated. The only reason it hasn't happened yet is because  
no one has stepped forward who would have the energy.

I'm sure ChrisD will gladly create the svn sandbox if we have  
volunteers lined up to get going.
