-# 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.

-File: dir Node: Top This is the top of the INFO tree

- Typing "q" exits, "?" lists all Info commands, "d" returns here,
