`-l' LOG-OPTION
===============

   Selects the form of logging to be made.  Two special "log-options"
are recognised.

  1. If "log-option" is the string `syslog', Amd will use the syslog(3)
     mechanism.

  2. If "log-option" is the string `/dev/stderr', Amd will use standard
     error, which is also the default target for log messages.  To
     implement this, Amd simulates the effect of the `/dev/fd' driver.

   Any other string is taken as a filename to use for logging.  Log
messages are appended to the file if it already exists, otherwise a new
file is created.  The file is opened once and then held open, rather
than being re-opened for each message.

   If the `syslog' option is specified but the system does not support
syslog or if the named file cannot be opened or created, Amd will use
standard error.  Error messages generated before Amd has finished
parsing the command line are printed on standard error.

   Using `syslog' is usually best, in which case Amd would be started
as follows:

     amd -l syslog ...
