# Modified for v4 of sysinfo_client, using extended tests for modules, files used and operating systems

# Underlying code remains unchanged

#

# find our location and use it for searching for libraries. library.pm must be in the same directory as the calling script

# or, if run interactively, in the parent of the modules
