contains a class that permits arbitrary large data storage
Memory_file is a generic_file class that only uses virtual memory.
this is the interface class from which all other data transfer classes inherit
this is the base class of object that can be allocated on a memory pool
libdar namespace encapsulate all libdar symbols
