Questions on Checking out files

[Lakshmi Sanjeevan]

Hi,

I have problems in checking out files from the repository. When I
checkout a directory from the repository I get the following error
message:

co error: unknown option: -x,v/
command format:
co -l[rev] -p[rev] -q[rev] -r[rev] -ddate -sstate -w[login] -jjoinlist
file ...
co aborted
cvs checkout: could not check out turn_tm

Can you help me out with this problem. May I know the reason for this type of error. What should I do to overcome this error?

Cheers,
 
Lakshmi
