 .SH DESCRIPTION
-\fIMhparam\fR writes the value of the specified profile component to the
-standard output separated by newlines.  If the profile component is not
-present, the default value (or nothing if there is no default) is printed.
-
-If the switch `\-component' is given, then the component name is displayed
+.B mhparam
+writes the value of the specified profile component to the standard
+output separated by newlines.  Component name matching is
+case-insensitive.  If the profile component is not present, the
+default value (or nothing if there is no default) is printed.
+.PP
+If the switch
+.B \-component
+is given, then the component name is displayed
 along with the profile components value.  This can be disabled with the
-switch `\-nocomponent'.
-
-If more than one component is specified in the `components' list, then
-the switch `\-component' is on by default.  If only one component is
-specified, then the switch `\-nocomponent' is on by default.
-
-If `\-all' is specified, then all components in the nmh profile are
+switch
+.BR \-nocomponent .
+.PP
+If more than one component is specified in the
+.I components
+list, then
+the switch
+.B \-component
+is on by default.  If only one component is
+specified, then the switch
+.B \-nocomponent
+is on by default.
+.PP
+If
+.B \-all
+is specified, then all components in the nmh profile are
 displayed and other arguments are ignored.
-
+.PP
+.B mhparam
+can provide other information, such as the
+.B nmh
+version identifier, the locations of the nmh
+.IR bindir ,
+.IR libexecdir ,
+.IR etcdir ,
+and
+.I docdir
+install directories, all
+.I proc
+settings, and the
+.I datalocking
+method described in the
+.IR mh\-profile (5)
+man page.  Information about the configuration of the
+.B nmh
+installation is also available, including the default mail spool
+locking method.  To test whether the configuration includes
+support for SASL, TLS,
+.IR iconv (3),
+and oauth, the following commands, respectively, will output a non-null
+string to indicate support:
+.PP
+.RS 5
+.nf
+mhparam\0sasl
+mhparam\0tls
+mhparam\0iconv
+mhparam\0oauth
+.fi
+.RE
+.PP
+Conversely, no output means that the specified support is not included.
+The
+.B \-debug
+switch displays all such other information available from
+.BR mhparam .
+.PP
+Note that the internal
+.B libdir
+component has been replaced by
+.BR libexecdir .
+The old form is deprecated and will be removed in a future release.
