sendpage - listen for pages via SNPP, and send pages via modem

       Kees Cook <kees@outflux.net>

       Oh, I bet this code is crawling with them.  :)  I've done my best to test this code,  but  I'm  only  one
       person.  If you find strange behavior, please let me know.

       sendpage is free software; it can be used under the terms of the GNU General Public License.

       Sendpage can run as the delivery agent, or as a client to insert a page into the paging queue.   For  the
       various  command-line  arguments,  the  idea here was to use sendmail-style arguments where I can, not to
       fully implement every option that sendmail has.  I just want the learning curve of sendpage to  be  small
       for people already familiar with sendmail.

/etc/sendpage/sendpage.cf
           Default  location  for  sendpage.cf,  which  holds  all  the  configuration information for sendpage,
           including Paging Central definitions, recipients, and various other behaviors.

       /var/spool/sendpage
           Default directory for all the Paging Central queues and pid files.

       /var/lock
           Default directory to keep the UUCP-style device locks.

       -bd Start  sendpage in "daemon mode" where it will start all the Paging Central queues and wait for pages
           to be delivered.  When sendpage runs as a daemon, it must  be  running  as  the  'sendpage'  user  as
           specified in the sendpage.cf file.

       -bp Display all the pages waiting in the Paging Central queues.

       -bv Try to expand the "recipient" name, using the recipient aliases specified in the configuration file.

       -bs Shutdown  the  running sendpage daemon and all its children.  If a Paging Central is in the middle of
           delivering a page, it will finish up and exit as soon as its current page is handled.

       -br This will send a SIGHUP to the master daemon.  When the master gets the SIGHUP, it will  re-read  its
           configuration  file,  and restart all the Paging Centrals.  It will wait for any busy Paging Centrals
           to finish before continuing.

       -bq This displays the state of the running daemons: Running or Not running.  If a pid file is stale  (the
           file exists, but the process doesn't), it will mark that pid as "Stale".

       -q[R pc]
           This  will send a SIGUSR1 signal to either the master daemon, or, if the Paging Central is specified,
           just that Paging Central in particular.  When the master gets a SIGUSR1, it will send it to  each  of
           the  running  Paging  Centrals.  If the Paging Central is not busy, it will immediately start a queue
           run.

       -C FILE
           Read the configuration file FILE instead of the default /etc/sendpage/sendpage.cf

       -h  Display a summary of all the available command line options.

       -d  Turn on debugging (like "debug=true" in /etc/sendpage/sendpage.cf)

       -f USER
           Show that the sent page is coming from USER.  Default is the current user.

       -m MESSAGE
           Send the given MESSAGE instead of reading text from stdin.

       -n  Do not notify the 'from' user about the status of the page.
