/*
 * NAME
 *      c++ - the C++ compiler cookbook
 *
 * DESCRIPTION
 *      This cookbook describes how to work with C++ files.
 *      Include file dependencies are automatically determined.
 *
 * RECIPES
 *      %.o: %.cpp      make object files form C++ source files
 *      %.o: %.cc       make object files form C++ source files
 *      %.o: %.c++      make object files form C++ source files
 *
 * VARIABLES
 *      c_incl          The C++ include dependency sniffer command.
 *                      Not altered if already defined.
 *      c++             The C++ compiler command
 *                      Not altered if already defined.
 *      c++_flags       options to pass to the C++ compiler command
 *                      Not altered if already defined.
 *                      The default is "-O".
 *      c++_include_flags Options passed to the C++ compiler and c_incl
 *                      controlling include file searching.
 *                      Not altered if already defined.
 *                      The default is empty.
 *      c++_src         C++ source files in the current directory.
 *      dot_src         Source files constructable in the current directory
 *                      (unioned with existing setting, if necessary).
 *      dot_obj         Object files constructable in the current directory
 *                      (unioned with existing setting, if necessary).
 *      dot_clean       Files which may be removed from the current directory
 *                      in a clean target.
 *
