+-.SH LOGGING
+-Pump logs a good deal of information to syslog, much of it at the DEBUG
+-level. If you're having trouble, it's a good idea to turn up syslog's logging
+-level.
+-
+-.SH CONFIG FILE
+-Pump supports a simple configuration file which lets you tune its behavior.
+-By default, it looks at \fI/etc/pump.conf\fR, though the \fB-c\fR option
+-lets you override that.
+-
+-The configuration file is line oriented, and most line contains a
+-directive followed by zero or more arguments. Arguments are handled
+-similar to how shells handle command arguments, allowing the use of
+-quotes and backslash escapes. Comments are allowed, and must begin with
+-a # character, and spaces and tabs are ignored.
+-
+-Directives may be specified at two levels, global and specific. Global 
+-directives change pump's behavior for all of the devices which it manages,
+-while specific directives change pump's behavior for a single device. 
++.SH "OPTION NOTES"
++The
++.B \-\-lookup\-hostname
++option causes
++.B pump
++to ignore the host and domain names returned by the server
++and instead
++to look these up in DNS using the IP address of the interface.
++The name that is looked up is used in forming the
++.B search
++line in the resolv.conf file.
++Thus, if either the
++.B \-\-no\-dns
++or
++.B domainsearch
++option is used then
++.B \-\-lookup\-hostname
++has no effect.
++.P
++Note that
++.B pump
++itself never sets the computer's hostname.
++
++.SH "CONFIGURATION FILE"
++You can tune the behavior of
++.B pump
++using a configuration file.
++By default
++.B pump
++reads \fI/etc/pump.conf\fR but you can change this using the
++\fB\-\-config\-file\fR option.
++
++The configuration file is line-oriented.
++Most lines contain a directive followed by zero or more arguments.
++Arguments are handled similarly to how shells handle command arguments,
++allowing the use of quotes and backslash escapes.
++Comments are allowed, and must begin with a # character.
++Spaces and tabs are ignored.
++
++Directives may be specified at two levels: global and specific.
++Global directives change
++.BR pump 's
++behavior for all of the devices that it manages
++whereas specific directives change
++.BR pump 's

+ Later directives always override earlier ones.

++At startup

++tries to detect whether another instance of itself is running.
++If the UNIX domain socket (normally \fI/var/run/pump.sock\fR)
++does not exist,
++.B pump
++tries to connect to tcp/127.0.0.1:68.
++If it is also unreacheable (possibly due to packet filtering),
++.B pump
++will issue a warning to stderr and assume that there is no
++instance of itself running.
