-## as follows:
-## lib_env(CXX) The compiler used to run testcases.
-## lib_env(CXXFLAGS) Special flags passed to the compiler.
-## lib_env(LIBGLOSSFLAGS) Flags for finding libgloss-using xcompilers.
-## lib_env(INCLUDES) Includes options to pass to the compiler.
-## lib_env(LIBS) Libraries to link, and dditional library flags.
-## lib_env(LIBTOOL) Path to the `libtool' script.
-## lib_env(SRC_DIR) Where V3 master source lives.
-## lib_env(BUILD_DIR) Where V3 is built.
-## lib_env(static) Flags to pass to the linker to build a
-## statically linked executable.
-## lib_env(shared) Flags to pass to the linker to build a
-## dynamically linked executable.
-## lib_env(testcase_options) Options specified by current testcase.
-## These are specified through the @xxx@-keywords.
