.SH NAME 
coffee \- Control the networked coffee machine
.SH SYNOPSIS
.B coffee [-s|--scorch] [-b|--blend
.I blend
.B ]
.I num_cups
.SH DESCRIPTION
.B coffee
sends a request to the remote coffee machine (usually the device 
.B /dev/cfpt0
to initiate a brew cycle to create
.I num_cups
of coffee.  It assumes the device is turned on and that the water and bean
reservoirs have sufficient stocks actually to complete the brew cycle.  For
those who prefer GNU's long options, they are supplied.
.SH OPTIONS
.TP
.B -s, --scorch
Scorch the coffee.  Rather than waiting for the brewed coffee to
age and oxidize on the warming plate, the freshly brewed coffee
is piped through a super-heating device, effectively simulating
the flavor of 6 oz. of liquid coffee that has been left on the
burner for 2 hours.
.TP
.B -b, --blend
Specify the blend of coffee to be brewed.
.I blend
is one of
.I regular, costarican , java,
or 
.I decaf.
If
.B -b 
.I blend
is not specified, the default
.I regular
(blech) is assumed.

.SH BUGS
You may have to get up out of your chair if the whole bean repository is 
empty.  Multiple successive requests queued to the same device can cause 
overflow.  Taking the last cup of coffee without starting a new pot is
a blight upon your soul and condemns you to everlasting damnation.
