#fix-info-dir was derived from update-info and gen-dir-node
# 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 "--").

-d, --delete delete invalid menu items (ignore missing menu items)
--debug print debug information to standard error path
--help print this help message and exit
--version print current version and exit
Backup of the info node has a '.old' suffix added. This is a shell script.

### output the dir header
cat<<DIR_FILE_END_OF_FILE
This is the file .../info/$DIR_FILE, which contains the
topmost node of the Info hierarchy, called ($DIR_FILE)Top.
The first time you invoke Info you start off looking at this node.
File: $DIR_FILE, Node: Top This is the top of the INFO tree
This (the Directory node) gives a menu of major topics.
Typing "q" exits, "H" lists all Info commands, "d" returns here,
"h" gives a primer for first-timers,
"mEmacs<Return>" visits the Emacs manual, etc.
In Emacs, you can click mouse button 2 on a menu item or cross reference
to select it.
