.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
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
displayed and other arguments are ignored.

Examples:

.nf
.ta \w'AliasFile:'u+2n
.in +.5i
% mhparam path
Mail

% mhparam mhlproc
%libdir%/mhl

% mhparam \-component path
Path: Mail

% mhparam AliasFile rmmproc
AliasFile: aliases
rmmproc: rmmproc

% mhparam \-nocomponent AliasFile rmmproc
aliases
rmmproc
