                      2: 
                      3: \fBMLP\fP stands for \fBM\fPultiple \fBL\fPine \fBP\fPrinter. It names a group
                      4: of programs that help users and applications access the computer's printers
                      5: in an orderly and efficient way.
                      6: 
                      7: Information to be printed is submitted to the \fBlp\fP program which makes a 
                      8: copy in a place called the "spool queue" and then notifies the scheduler.  The
                      9: scheduler (\fBlpsched\fP) periodically scans the queue looking for requests
                     10: that are waiting to print.  When it finds one, it assigns a printer to do the
                     11: job.  If the desired printer is busy, then the request will be reconsidered when
                     12: the device becomes available.  Requests are normally held in the queue for a
                     13: certain period of time so that they may be reprinted if the user so wishes.
                     14: Every few minutes, the scheduler purges requests that have grown too old.  The
                     15: scheduler also maintains a log of its activities and reports anything unusual
                     16: to either the system administrator or the appropriate user through the email
                     17: facility.
                     18: 
                     19: \fBMLP\fP replaces the spooler distributed with COHERENT 4.0.  Using the
                     20: existing spooler in conjunction with \fBMLP\fP is not recommended since they
                     21: do not know how to share the printers with each-other.
                     22: 
                     23: The following programs comprise the \fBMLP\fP system:
