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.
