Exactly. This is sort of like asking what private IP address
range you should use for a local network. In that case the
answer is one that isn't used by a company you might merge
with... Likewise for software you just need to use a space
that no one else will use. Things that install from source
usually go under /usr/local by default with a configure
option to move elsewhere. Packaged items that aren't part
of a standard distribution often go under /opt.
