HELP! Howto disable binary flags on files

[Bruce]

We've just discovered that someone checked in or changed a whole slew
of files in our CVS tree to be handled as binary files when, in fact,
none of these files are binary at all. This has caused us to not be
able to diff, merge, etc. - which is obviously a major problem. I want
to know if there is any method of disabling the binary flags on these
files in CVS. Does anyone know of a relatively easy method of doing
this type of operation?

Thanks,
Bruce
