27 | The results, which go to standard output or to a file | |

29 | are entries containing function or variable names and their documentation. | |
30 | Each entry starts with a ^_ character. | |
31 | Then comes F for a function or V for a variable. | |
32 | Then comes the function or variable name, terminated with a newline. | |
33 | Then comes the documentation for that function or variable. | |
