We use Oracle Forms Developer as a front end for Oracle 8i, this is a little "offtopic" but maybe someone can give a hint on this.

As a team of developers we want something like CVS to control our source code, the thing is that the code generated by the Forms Developer FrameWork is not plain text, so everytime I checkout, check-in or merge a file is a really mess, sometimes I can't even open the files in Forms Developer again...
Some of the developers want to have a lock schema of the forms so nobody can edit the files while someone is using it already(CVS is against this schema).

My question is: Is there any tool available for free that can help us with this ?
thanks in adavance for any tip.
