(de)centralized ports management with portsnap

[David Newman]

I'm setting up a group of FreeBSD servers that use 'portsnap fetch' and
then 'portsnap update' to refresh their ports trees.

Can I set up a local master to avoid pulling updates multiple times? If
portsnap isn't the right tool for this, what is?

Apologies if this has been asked before; this seems like a standard
problem, but I didn't see an answer in a web search, the portsnap
manpage, or in the Michael W. Lucas FreeBSD book.

thanks
