+--  This procedure is the project-aware driver for the GNAT tools.
+--  For gnatls, gnatxref, gnatfind and gnatstub, it setup the environment
+--  variables ADA_INCLUDE_PATH and ADA_OBJECT_PATH and gather the switches
+--  and file names from the project file (if any) and from the common line,
+--  then call the non project-aware tool (gnatls, gnatxref, gnatfind or
+--  gnatstub).
+--  For other tools (compiler, binder, linker, gnatmake), it invokes
+--  gnatmake with the proper switches.
