NAME
       mhparam - print nmh profile and context components

SYNOPSIS
       mhparam [components] [-all] [-component | -nocomponent] [-version]
	    [-help] [-debug]

DESCRIPTION
       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.

       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 spec‐
       ified, then the switch -nocomponent is on by default.

       If  -all	 is specified, then all components in the nmh profile are dis‐
       played and other arguments are ignored.

       mhparam can provide other information, such as the locations of the nmh
       etcdir  and  libdir  install  directories  and  all proc settings.  The
       -debug switch  displays	all  such  other  information  available  from
       mhparam.

       Examples:

	    % mhparam path
	    Mail

	    % mhparam mhlproc
	    /usr/lib/mhl

	    % mhparam -component Path
	    Path: Mail

	    % mhparam AliasFile rmmproc
	    AliasFile: aliases
	    rmmproc: rmmproc

	    % mhparam -nocomponent AliasFile rmmproc
	    aliases
	    rmmproc

	    % mhparam path nonexistent context
	    Path: Mail
	    context: context

	    % mhparam etcdir
	    /etc/nmh

	    % mhparam libdir
	    /usr/lib

       mhparam is also useful in back-quoted operations:

	    % fgrep cornell.edu `mhpath +`/`mhparam aliasfile`

EXIT STATUS
       mhparam returns the number of components that were not found.
