[cvsnt] prevent binaries to be added to the repository

[Dulat Simon]

Hi there,
it would be great if someone could help me out.
I would like to prevent users from being able to add binary files to the
repository.
I tried the following with CVSROOT/commitinfo:
commitinfo checks if a file contains one of the following endings:
*.obj, *.exe, ... and aborts commit if a file with one of those endings
is found.
This works fine for new files being added to the repository, or I should
better say this works fine for new files being committed to the
repository.
Problem is: this approach doesn't work if a user tries to remove an
existing binary file from the repository.
A solution would be to prevent the initial adding of the file (not the
following commit after a file was added). Is there a (administrative)
file which controls "cvs add"?

Thanks a lot in advance for your help!

Cheers,
Simon
