25 | The results, which go to standard output or to a file | |
26 | specified with -a or -o (-a to append, -o to start from nothing), | |
27 | are entries containing function or variable names and their documentation. | |
28 | Each entry starts with a ^_ character. | |
29 | Then comes F for a function or V for a variable. | |
30 | Then comes the function or variable name, terminated with a newline. | |
31 | Then comes the documentation for that function or variable. | |
