don't use spaces at the beginning of a line where tabs are normally
used (the worst thing was that half of this file was right (tabs) and
half was wrong (spaces), making for painful reading).

/usr/bin/lock can be used to lock a terminal much like xlock does
for your X-windows session. Problem is, /usr/bin/lock cannot lock
your terminal indefinately. Rather you must specify a timeout
value, after which, your terminal is unlocked and become unsecured.
I have added a ``-n'' no timeout option to /usr/bin/lock
Currently the only way to get this functionality is to use a huge
timeout value and hope it is long enought (in time). This method
also requires you to know the maxium number of minutes you are
allowed to specify.
