Building 5.x binaries on 6.2-RELEASE

[Brian Hourigan]

I'm involved in some software development and we need to provide 
precompiled binaries for FreeBSD 5.x from a 6.2-RELEASE system

I checked through the documentation on the pointyhat package building 
cluster, it mentions the machines run 7.0-CURRENT and produces binaries 
for 5.x and 6.x.. but I can't find the scripts or any documentation on how 
exactly this is accomplished

If anyone has any information please point me in the right direction, 
thanks!

Sincerely,

Brian Hourigan
