Class Method Details

.auto_conf ⇒ Object

Automatically configures a TEM.

In case of success, the $tem global variable is set to a Tem::Session that can be used to talk to some TEM. An exception will be raised if the session creation fails.

It is safe to call auto_conf multiple times. A single session will be open.
