/usr/local or /opt? which is better?

[Zhao YouBing <zhaoyb@cad.zju.edu.cn>]

for install programs?

It think the FHS doesn't state it very clearly.

There are some difference anyway, /usr/local is for local group access 
and /opt can  be made globally sharable,
but besides that are there any factors more important which can tell me 
which should be my dest dir when I install some program?
