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.
