27 /* The arguments given to this program are all the C and Lisp source files | |
930 | 28 of XEmacs. .elc and .el and .c files are allowed. |
29 A .o or .obj file can also be specified; the .c file it was made from is used. | |
30 This helps the makefile pass the correct list of files. | |
31 | |
32 The results, which go to standard output or to a file | |
33 specified with -a or -o (-a to append, -o to start from nothing), | |
34 are entries containing function or variable names and their documentation. | |
35 Each entry starts with a ^_ character. | |
36 Then comes F for a function or V for a variable. | |
37 Then comes the function or variable name, terminated with a newline. | |
38 Then comes the documentation for that function or variable. | |
39 | |
40 Added 19.15/20.1: `-i site-packages' allow installer to dump extra packages | |
41 without modifying Makefiles, etc. | |

930 | 985 For defun, defmacro, and autoload, we know how to skip over the |
986 arglist, but the doc string must still have a backslash and newline | |
987 immediately after the double quote. | |
988 The only source files that must follow this convention are preloaded | |
989 uncompiled ones like loaddefs.el and bindings.el; aside | |
428 | 990 from that, it is always the .elc file that we look at, and they are no |
991 problem because byte-compiler output follows this convention. | |
992 The NAME and DOCSTRING are output. | |
993 NAME is preceded by `F' for a function or `V' for a variable. | |
994 An entry is output only if DOCSTRING has \ newline just after the opening " | |
3368 | 995 |
996 Adds the filename a symbol or function was found in before its docstring; | |
997 there's no need for this with the load-history available, but we do it for | |
998 consistency with the C parsing code. | |
