Problem with cvsweb

[josem_rodriguezy at ieci.es]

Hello,
I have a problem with cvsweb configuration.
I read the install instruction but cvsweb dont work

The error is:
Error: $cvstreedefault points to a repository (local) not defined in %CVSROOT
(edit your configuration file /binarios/httpd-2.0.47/conf/cvsweb.conf)

May you help me with any suggestion?
Have you an installation manual?

Thank you
Jose
