@defun APROPOS (string &optional (package nil))
7
Prints those symbols whose print-names contain STRING as substring.
8
If PACKAGE is non-NIL, then only the specified package is searched.
13
@defun INFO (string &optional (list-of-info-files *default-info-files*))
16
Find all documentation about STRING in LIST-OF-INFO-FILES. The search
17
is done for STRING as a substring of a node name, or for STRING in the
18
indexed entries in the first index for each info file. Typically that
19
should be a variable and function definition index, if the info file is
20
about a programming language. If the windowing system is connected,
21
then a choice box is offered and double clicking on an item brings up
24
Otherwise a list of choices is offered and the user may select some of
27
list-of-info-files is of the form
29
("gcl-si.info" "gcl-tk.info" "gcl.info")
31
The above list is the default value of *default-info-files*,
32
a variable in the SI package. To find these files in the file
33
system, the search path *info-paths* is consulted as is the master
34
info directory @file{dir}.
36
see *Index *default-info-files*:: and *Index *info-paths*::.

0: DEFUN :(gcl-si.info)Special Forms and Functions.

Enter n, all, none, or multiple choices eg 1 3 : 1

Info from file /home/wfs/gcl-doc/gcl.info:
47
---------------------------------------------------------------------------
48
`Defun' function-name lambda-list [[@{declaration@}* | documentation]]
52
would list the node @code{(gcl.info)defun}.
53
That is the node entitled @code{defun} from the info file gcl.info. That
54
documentation is based on the ANSI common lisp standard. The choice
56
DEFUN :(gcl-si.info)Special Forms and Functions.
59
refers to the documentation on DEFUN from the info file gcl-si.info in
60
the node @i{Special Forms And Functions}. This is an index reference
61
and only the part of the node which refers to @code{defun} will be
65
(info "factor" '("maxima.info"))
67
would search the maxima info files index and nodes for @code{factor}.
78
A list of strings such as
80
'("" "/usr/info/" "/usr/local/lib/info/" "/usr/local/info/"
81
"/usr/local/gnu/info/" )
83
saying where to look for the info files. It is used implicitly
84
by @code{info}, see *Index info::.
86
Looking for maxima.info would look for the file
87
maxima.info in all the directories listed in *info-paths*. If nto found
88
then it would look for @file{dir} in the *info-paths* directories,
89
and if it were found it would look in the @file{dir} for a menu item
93
* maxima: (/home/wfs/maxima-5.0/info/maxima.info).
97
If such an entry exists then the directory there would be used for the
98
purpose of finding @code{maxima.info}
