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.

897 and we use that instead of reading a doc string within that defining-form.

900 formatting convention: all docstrings must appear on the same line as the
|
|
930
|
901 initial open-paren (the one in column zero) and must contain a backslash
|
|
|
902 and a newline immediately after the initial double-quote. No newlines
|
|
428
|
903 must appear between the beginning of the form and the first double-quote.
|
|
930
|
904 For defun, defmacro, and autoload, we know how to skip over the
|
|
|
905 arglist, but the doc string must still have a backslash and newline
|
|
|
906 immediately after the double quote.
|
|
|
907 The only source files that must follow this convention are preloaded
|
|
|
908 uncompiled ones like loaddefs.el and bindings.el; aside
|
|
428
|
909 from that, it is always the .elc file that we look at, and they are no
|
|
|
910 problem because byte-compiler output follows this convention.
|
|
|
911 The NAME and DOCSTRING are output.
|
|
|
912 NAME is preceded by `F' for a function or `V' for a variable.
|
|
|
913 An entry is output only if DOCSTRING has \ newline just after the opening "
