-/// Class implementing the GDB RSP debug server for the NaCl applications.
-/// It creates illusion to the client (debugger), that it debugs NaCl
-/// application (aka nexe), hidding all other intermediate processes,
-/// such as chrome + sel_ldr. It also hides all non-nexe threads.
-/// For example of how to use it, look in nacl-gdb_server.cc.
-///
-/// Note: current implementation has roughly the same set of features as
-/// in-process debug stub (major difference is the support of Win32).
-/// In order to be compatible with current VisualStudio debugger plugin,
-/// it's also limited to one nexe per session.
