print-cdrom-packages.sh??

[Howard Jones]

Moving on with my automated installs, I want to build some additional 
packages into the FTP area of my install server, which was seeded from 
the 6.1-RELEASE ISOs.

The "FreeBSD Release Engineering for Third Party Software Packages" 
document on the FreeBSD website says that the release-building process 
uses a script called print-cdrom-packages.sh to produce the list of 
packages to build. However, my source tree doesn't have this script, and 
a look in CVS suggests that it's no longer in use, and hasn't been since 
March 2005 (Revision 1.71, Mon Mar 21 19:19:24 2005 UTC - Retire 
print-cdrom-packages.sh as it has been replaced.).

Is there any current documentation for how the package building process 
is done? Or am I looking at the wrong URL? 
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/releng-packages/article.html

Ultimately, I'll want to rebuild all the packages, so just getting the 
few extras I need right now doesn't really help. I intend to use 'make 
release' to keep a 6_RELENG install with fairly current packages 
available for new servers, so I don't need to do so much rebuilding 
immediately after a fresh install.

Thanks in advance for any pointers, or even any "don't do that, do this 
instead"-type advice.
