24 /* The arguments given to this program are all the C and Lisp source files
|
|
|
25 of XEmacs. .elc and .el and .c files are allowed.
|
|
|
26 A .o file can also be specified; the .c file it was made from is used.
|
|
|
27 This helps the makefile pass the correct list of files.
|
|
|
28
|
|
|
29 The results, which go to standard output or to a file
|
|
|
30 specified with -a or -o (-a to append, -o to start from nothing),
|
|
|
31 are entries containing function or variable names and their documentation.
|
|
|
32 Each entry starts with a ^_ character.
|
|
|
33 Then comes F for a function or V for a variable.
|
|
|
34 Then comes the function or variable name, terminated with a newline.
|
|
|
35 Then comes the documentation for that function or variable.
|
|

|
36
|
|
|
37 Added 19.15/20.1: `-i site-packages' allow installer to dump extra packages
|
|
|
38 without modifying Makefiles, etc.

705 initial open-paren (the one in column zero) and must contain a backslash

|

706 and a double-quote immediately after the initial double-quote. No newlines
|
|
|
707 must appear between the beginning of the form and the first double-quote.
|
|
|
708 The only source file that must follow this convention is loaddefs.el; aside
|
|
|
709 from that, it is always the .elc file that we look at, and they are no
|
|
|
710 problem because byte-compiler output follows this convention.
|
|
|
711 The NAME and DOCSTRING are output.
|

712 NAME is preceded by `F' for a function or `V' for a variable.
