P2
Yes, you read it right the letter P, then the number 2. It can stands for the followings in no particular order:
- Provisioning Platform
- Provisioning Partout (partout is the french word for everywhere)
- Pascal's Provisioning (hey, why not? We do have the "Ed Merks Framework")
- Provisioning, the 2nd generation
The bundles and packages will be renamed right after M2 has been delivered.
The motivations behind this renaming can be found at http://wiki.eclipse.org/Equinox_Provisioning_Naming.
