This patch implements what was discussed on erlang-questions in regards to allowing plug-in db modules to replace cs_db_otp. It adds a header file, database.hrl, which defines the constant DB, defaulting to cs_db_otp. Wherever cs_db_otp was referenced throughout the application, it has been replaced by ?DB.

Thanks, but the patch seems not to contain the additional/new files, like database.hrl.

Sorry about the incomplete patch. This one includes database.hrl (I forgot to svn add it before generating the last patch).

Thanks Jason, I applied your patch in revision #17
