mhparam - print mmh profile and context components
mhparam [components] [-all] [-component | -nocomponent] [-debug] [-Version] [-help]
mhparam 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 mmh profile and context (including comments) are displayed and other arguments are ignored.
If -debug is specified, then a defined set of internal profile entries are displayed.

mhparam is also useful in back-quoted operations:
% fgrep cornell.edu `mhpath +`/`mhparam aliasfile`
mhparam returns the number of components that were not found.
