1INCLAN: info - variable to control the amount of information

"info" is a variable that determines which messages are written to standard
output and into the protocol file. The possible settings are:

none    No messages are written.
minimal A minimal set of messages is written, in general a single line for
        each command that is executed.
normal  The "normal" amount of messages is written.
full    The "full" amount of messages is written.
debug   The "full" amount of messages and additional undocumented messages
        for debug purposes are written.

Optionally, this variable may have two of the above values, separated by a
comma. In this case, the first value applies to standard output, the second
to the protocol file.
