"copy_directory, copy_if_different, echo, echo_append, environment, "
"make_directory, md5sum, remove, remove_directory, rename, tar, time, "
"touch, touch_nocreate. In addition, some platform specific commands "
"are available. "
"On Windows: comspec, delete_regv, write_regv. "
"On UNIX: create_symlink."},

"CMake cache that are not marked as INTERNAL or ADVANCED. This will "
"effectively display current CMake settings, which can then be changed "
