That's right.

Our CVS repository can be accessed by the command:

	cvs -d:pserver:guest@REDACTED:/hipe checkout otp

It allows for read access only.  We welcome any change that makes HiPE 
working and/or more robust in some platform.  However, for the change to 
be included in the distribution, it will need to be reviewed by us.
