This configuration step (the Inventory script) takes inventory of
the lsof distribution.  The script runs for a minute or two while
it checks that all the subdirectories, information files, scripts,
header files and source files that should be present really are.

It's not absolutely necessary that you take inventory, but it's a
good idea to do it right after the lsof distribution has been
unpacked.  Once the inventory has been taken, this script creates
the file ./.ck00MAN as a signal that the inventory step has been
done.

You can call the Inventory script directly at any time to take
inventory.  You can inhibit the inventory step permanently by
creating the file ./.neverInv, and you can tell the Configure script
to skip the inventory and customization steps with the -n option.
