@rem ------------------------ Subroutines ---------------
@rem routine to do comparison of semantic version numbers
@rem found at https://stackoverflow.com/questions/15807762/compare-version-numbers-in-batch-file
:compareVersions
::
:: Compares two version numbers and returns the result in the ERRORLEVEL
::
:: Returns 1 if version1 > version2
::         0 if version1 = version2
::        -1 if version1 < version2
::
:: The nodes must be delimited by . or , or -
::
:: Nodes are normally strictly numeric, without a 0 prefix. A letter suffix
:: is treated as a separate node
