Templates cvswrappers

[Ed J]

Where can I find usable templates for a cvswrappers file?  My server's
cvswrapper file is empty.  I'm looking for a resource that tells me which
file extensions are binary for any given software application (e.g. Orcad,
AutoCAD).

I've been using TortoiseCVS from Windows, with a Linux-based cvs server, and
have survived with a blank cvswrappers because TortoiseCVS automatically
deciphering binary vs. text when I added files to the repository.  Now, I
need to use a separate cvs command-line client to get an "import" capability
(to preserve file timestamps), and the empty cvswrappers file is corrupting
my binary files by treating them as text.

Thanks in advance,
