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 NAME
+.Nm man.conf
+.Nd
+.Xr man 1
+and
+.Xr manpath 1
+configuration files
+.Sh DESCRIPTION
+The
+.Nm
+file is used to configure the manual search path, locales, and utility set for
+.Xr man 1
+and its related utilities.
+During initialization,
+.Xr man 1
+reads the configuration files located at
+.Pa /usr/local/etc/man.d/*.conf
+and
+.Pa /etc/man.conf .
+.Pp
+The files contained in
+.Pa /usr/local/etc/man.d/*.conf
+are intended to be used by the
+.Xr ports 7
+system for extending the manual set to support additional paths and locales.
+.Pa /etc/man.conf
+is intended to be used by the local administrator to set additional policy.
+.Pp
+Currently supported configuration variables include:
+.Bl -tag -offset indent
+.It MANCONFIG
+Overrides the default location to import additional manual configuration files.
+Defaults to
+.Pa /usr/local/etc/man.d/*.conf .
+.It MANPATH
+Adds the specified directory to the manual search path.
+.It MANLOCALE
+Indicates support is available for the given locale.
+.El
+.Pp
+For pages in a given language, overriding the default toolset for
+display is supported via the following definitions:
+.Bl -tag -offset indent -compact
+.It EQN Ns _ Ns Va LANG
+.It COL Ns _ Ns Va LANG
+.It NROFF Ns _ Ns Va LANG
+.It PIC Ns _ Ns Va LANG
+.It TBL Ns _ Ns Va LANG
+.It TROFF Ns _ Ns Va LANG
+.It REFER Ns _ Ns Va LANG
+.It VGRIND Ns _ Ns Va LANG
+.El
+.Pp
+See the
+.Sx EXAMPLES
+section for how to use these variables.
+.Sh IMPLEMENTATION NOTES
+The parser used for this utility is very basic and only supports comment
+characters (#) at the beginning of a line.
+.Sh FILES
+.Bl -tag -compact
+.It Pa /etc/man.conf
+System configuration file.
+.It Pa /usr/local/etc/man.d/*.conf
+Local configuration files.
+.El
+.Sh EXAMPLES
+A perl port that needs to install additional manual pages outside of the
+default location could install a file in
+.Pa /usr/local/etc/man.d/perl.conf
+with the following contents:
+.Bd -literal -offset indent
+# Add perl man pages to search path
+MANPATH /usr/local/lib/perl5/5.8.9/man
+MANPATH /usr/local/lib/perl5/5.8.9/perl/man
+.Ed
+.Pp
+A Japanese localization port could install a custom toolset and include a
+file in
+.Pa /usr/local/etc/man.d/ja-man-doc.conf
+with the following contents:
+.Bd -literal -offset indent
+# Setup Japanese toolset
+MANLOCALE	ja_JP.eucJP
+EQN_JA		/usr/local/bin/gepn
+PIC_JA		/usr/local/bin/gpic
+TBL_JA		/usr/local/bin/gtbl
+NROFF_JA	/usr/local/bin/groff -man -dlang=ja_JP.eucJP
+TROFF_JA	/usr/local/bin/groff -man -dlang=ja_JP.euc.jp
+.Ed
+.Pp
+If the system administrator decides to override the
+.Va LOCALBASE
+.Xr make 1
+variable causing all
+.Xr ports 7
+to be installed into
+.Pa /opt
+instead of
+.Pa /usr/local ,
+specifying the following in
+.Pa /etc/man.conf
+will accommodate this change:
+.Bd -literal -offset indent
+# Look for additional configuration files
+MANCONFIG /opt/etc/man.d/*.conf
