Accessing MySQL with mysql.sock in another location

[Ben Rubinstein]

A client reports being unable to use a tool I wrote; he gets the message 
"Can't connect to local MySQL server through socket /tmp/mysql.sock".

Apparently, his MySQL installation puts mysql.sock into another directory. 
He's reluctant to change this because he has a setup with various other things 
accessing MySQL succesfully.

Is there a way to configure Rev's database client to access mysql.sock at a 
location other than /tmp/mysql.sock ?

TIA,
