# Generate the top-level Info node, given a directory of Info files
|
||
# and (optionally) a skeleton file. The output will be suitable for a
|
||
# top-level dir file. The skeleton file contains info topic names in the
|
||
# order they should appear in the output. There are three special
|
||
# lines that alter the behavior: a line consisting of just "--" causes
|
||
# the next line to be echoed verbatim to the output. A line
|
||
# containing just "%%" causes all the remaining filenames (wildcards
|
||
# allowed) in the rest of the file to be ignored. A line containing
|
||
# just "!!" exits the script when reached (unless preceded by a line
|
||
# containing just "--"). Once the script reaches the end of the
|
||
# skeleton file, it goes through the remaining files in the directory
|
||
# in order, putting their entries at the end. The script will use the
|
||
# ENTRY information in each info file if it exists. Otherwise it will
|
||
# make a minimal entry.

This is the file .../info/dir, which contains the topmost node of the
|
||
Info hierarchy. The first time you invoke Info you start off
|
||
looking at that node, which is (dir)Top.
|
||
|
||
File: dir Node: Top This is the top of the INFO tree
|
||
This (the Directory node) gives a menu of major topics.
|
||
Typing "d" returns here, "q" exits, "?" lists all INFO commands, "h"
|
||
gives a primer for first-timers, "mTexinfo<Return>" visits Texinfo topic,
|
||
etc.
|
||
Or click mouse button 2 on a menu item or cross reference to select it.
|
||
--- PLEASE ADD DOCUMENTATION TO THIS TREE. (See INFO topic first.) ---
|
||
|
||
* Menu: The list of major topics begins on the next line.
