XXX: improve this paragraph: The input for the code generator is standard C++ code (in fact we use gccxml to parse the C++ code and the code generator takes the XML as input) and you mark the procedures you want to expose to other processes. + It then generates the stubs needed. + The exported procedures can be grouped. For each group the code generator is called which generates 6 outputfiles: group_common.hxx, group_common.cpp, group_client.hxx, group_client.cpp, group_server.hxx, group_server.cpp. The _common files are used by client and server whereas the _client files are used by the client and the _server files by the server. + + \section install_sec Installation + + \subsection requirements Requirements + - boost (serialization ) + - gccxml + - libxmlpp + + \section usage Usage example + + In this example we create two packages: + - server program and library to connect to the server.
