Scripted CVS updates?

["Gonyou, Austin" <austin@xxxxxxxxxxxxxxx>]

I'm trying to script cvs updates with cron for once every couple of days, or
once a week. But, I must provide a login password to the cvs server. Is
there a way to do that easily? perhaps something like?

cvs login<< EOF
password

EOF

Thanks in advance.
