/**
 * @file mca_base_component_repository.h
 *
 * This file provide the external interface to our base component
 * module.  Most of the components that depend on it, will use the
 * retain_component() function to increase the reference count on a
 * particular component (as opposed to the retain() function, which is
 * internal to the opal/mca/base).  But it's convenient to have all
 * the functions exported from one header file rather than to separate
 * retain_component() and retain() into two separate header files
 * (i.e., have a separate header file just for retain()).
