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

|
741 For defun, defmacro, and autoload, we know how to skip over the arglist.
|
|
|
742 For defvar, defconst, and fset we skip to the docstring with a kludgy
|
|
|
743 formatting convention: all docstrings must appear on the same line as the
|
|
|
744 initial open-paren (the one in column zero) and must contain a backslash
|
|
|
745 and a double-quote immediately after the initial double-quote. No newlines
|
|
|
746 must appear between the beginning of the form and the first double-quote.
|
|
|
747 The only source file that must follow this convention is loaddefs.el; aside
|
|
|
748 from that, it is always the .elc file that we look at, and they are no
|
|
|
749 problem because byte-compiler output follows this convention.
|
|
|
750 The NAME and DOCSTRING are output.
|
|
|
751 NAME is preceded by `F' for a function or `V' for a variable.
|
|
|
752 An entry is output only if DOCSTRING has \ newline just after the opening "
