Implementaiton of man, manpath, whatis, and apropos written entirely in sh.

Features of this new version in favor of the old one:
BSD licensed -- old one is GPL.
Imports configuration from /etc/man.conf and LOCALBASE/etc/man.d/*.conf
allowing ports to extend the base functionality. The pluggable
configuration can supplement the manual search path (retiring use.perl),
add locales, and override language specific toolsets (attempt to merge
the japanese/man port into the base system as much as possible).

Much effort has been made to make this version mirror the functionality
of the existing implementation. For 99% of users, it should be a drop in
replacement.

+.Sh SYNOPSIS
+.Nm
+.Op Fl Ldq
+.Sh DESCRIPTION
+The
+.Nm
+utility determines the user's manual search path from
+the user's
+.Ev PATH ,
+and local configuration files.
+This result is echoed to the standard output.
+.Bl -tag -width ".Fl d"
+.It Fl L
+Output manual locales list instead of the manual path.
+.It Fl d
+Print extra debugging information.
+.It Fl q
+Suppresses warning messages.

+.Sh IMPLEMENTATION NOTES
+The
+.Nm
+utility constructs the manual path from two sources:
+.Bl -enum -compact
+.It
+From each component of the user's
+.Ev PATH
+for the first of:
+.Bl -dash -compact
+.It
+.Pa pathname/man
+.It
+.Pa pathname/MAN
+.It
+If pathname ends with /bin:
+.Pa pathname/../man
+.El
+Note: Special logic exists to make
+.Pa /bin
+and
+.Pa /usr/bin
+look in
+.Pa /usr/share/man
+for manual files.
+.It
+The configuration files listed in the
+.Sx FILES
+section for
+.Va MANPATH
+entries.
+.El
+The information from these locations is then concatenated together.
+.Pp
+If the
+.Fl L
+flag is set, the
+.Nm
+utility will search the configuration files listed in the
+.Sx FILES
+section for
+.Va MANLOCALE
+entries.
+.Sh ENVIRONMENT
+The following environment variables affect the execution of
+.Nm :
+.Bl -tag -width ".Ev MANLOCALES"
+.It Ev MANLOCALES
+If set with the
+.Fl L
+flag, causes the utility to display a warning and the value, overriding any
+other configuration found on the system.
+.It Ev MANPATH
+If set, causes the utility to display a warning and the value, overriding
+any other configuration found on the system.
+.It Ev PATH
+Influences the manual path as described in the
+.Sx IMPLEMENTATION NOTES .
