This script will check certain settings/entries of your PNP environ-
ment to assist you in finding problems when you are using PNP.
It may be used prior and during operation of PNP.
Output starts with a letter with the following meaning:
[INFO] informational message about settings, ...
[OK ] ok message, will not affect the operation of PNP
[WARN] warning message, might effect the operation of PNP
[CRIT] error message: PNP will not work without resolving the problem(s)
[HINT] hint: it might be worth reading the appropriate documentation
[DBG ] debugging message, hopefully showing the source of your problem
