hpx/components.hpp

The header hpx/include/components.hpp includes the components implementation. A component in hpx is a C++ class which can be created remotely and for which its member functions can be invoked remotely as well. More information about how components can be defined, created, and used can be found in Writing components. Components and actions includes examples on the accumulator, template accumulator and template function accumulator.
