# Assume sysinfo-client in parent directory, so just run it and have it tell us it's version

# 20250330 RWR v1.2.1
# For Windows compatility, added 'perl' before calling perl script
#

# 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
