Substitute paths into man pages
Generate the man pages for zwgc, zctl, zhm, and zephyrd at build time, so they can refer to the paths actually used instead of whatever was used on Athena in the 1980's.

+.SH NAME
+zephyrd \- Zephyr server daemon
+.SH SYNOPSIS
+.I @sbindir@/zephyrd
+[
+.BI \-d
+]
+.SH DESCRIPTION
+.I zephyrd
+is the central server for the Zephyr Notification System.
+It maintains a location database of all currently logged-in users, and a
+subscription database for each user's Zephyr clients.
+.PP
+.I zephyrd
+communicates with daemons running on other Zephyr server hosts, to
+provide a reliable service.
+.PP
+While running, any unusual conditions are recorded via
+.I syslog(3)
+to facility local6 at various levels.
+The
+.BI \-d
+option enables logging of additional debugging information.
+.PP
+When a
+.B zephyrd
+is executed, it requests a list of server machines from Hesiod and
+initializes its state from any
+\fIzephyrd\fRs executing on the other known servers. This initialization
+is only performed after the \fIzephyrd\fRs have authenticated themselves
+to each other via Kerberos.
+The server then enters a dispatch loop, servicing requests from clients and
+other servers.
+.SH SIGNALS
+.B SIGUSR1
+enables logging of additional debugging information.
+.br
+.B SIGUSR2
+disables the logging of additional debugging information.
+.br
+.B SIGHUP
+causes
+.I zephyrd
+to re-read the default subscription file and to re-query Hesiod about
+valid peers. Any peers which are not responding and no longer
+mentioned in Hesiod are flushed; any peers not previously named by
+Hesiod are added.
+.br
+.B SIGINT \fRand\fB SIGTERM
+cause
+.I zephyrd
+to gracefully shut down.
+.br
+.B SIGFPE
+causes
+.I zephyrd
+to dump the location and subscription databases to
+.I /var/tmp/zephyr.db
+in an ASCII format.
+.SH ACCESS CONTROL
+Certain notice classes are restricted by the Zephyr server. Each such
+class has access control lists enumerating who may transmit (xmt-*.acl) or
+subscribe to that particular class. Subscriptions may be
+restricted either absolutely (sub-*.acl files), or by instance restrictions.
+iws-*.acl files control subscriptions to wildcarded instances.
+iui-*.acl files control subscriptions to instances which are not the
+Kerberos principal identity of the subscriber.
+If an access control list of a given type is absent, there is no
+restriction of that type on the class, except that any notices of the
+class must be authenticated.
+The class registry lists all classes which are restricted.

+.SH BUGS
+The current implementation of the Zephyr server (\fIzephyrd(8)\fR) makes
+no distinction between realm-announced, net-visible and net-announced
+exposure levels.
