TortoiseCVS and text/binary files

[Jason Allen]

Anybody know how to tell TortoiseCVS that certian filetypes should always be added as text and others should always be added as binary? I have a large directory structure and most of the directories have a small text file with a .plf extension. When I add all these directories to the CVS server using TortoiseCVS, it will continuosly prompt me whether the plf files are text or binary. I'd like to be able to specify that all files of a certian extension are text.   Thanks,   Jason A.
