23 | of GNU Emacs. .elc and .el and .c files are allowed. | |
24 | A .o file can also be specified; the .c file it was made from is used. | |
25 | This helps the makefile pass the correct list of files. | |
08a39b83 | 26 | Option -d DIR means change to DIR before looking for files. |

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

b0f08a24 DL |
