Yes. The PDEMapProvider will start by loading all of the map files that
it finds in the designated folder and build an in-memory catalog of all
the components.

The only regexp mapping that occurs is when the resolver determines what
searchPath that should be use. Once that has been determined, each
provider found in that search path is consulted. If a PDEMapProvider is
encountered, and if any of the maps that resides in the folder that it
appoints contains the desired component, then that provider has found a
match. It will then delegate to the provider that the actual map entry
is pointing to (typically cvs).
