=head1 mkrmcresources
|
|
=head2 mkrmcresources is used to predefine RMC conditions, responses, associations,
|
|
sensors (and can be extended to support any RSCT resource
|
|
class).
|
|
To use the command, create perl modules in a directory. Each resource
|
|
should have its own perl module (so that it is easy to update a
|
|
resource without interfering with other resources),
|
|
and should be named <Resource Name>.pm.
|
|
After the resource perl modules are installed, they will be created
|
|
by the next execution of the this command.
|
|
This command should be called by the post install scripts
|
|
of packaging files, script run after install or from the command line.
