def msi_conformant_version():
'''
An msi installer uninstalls/replaces a lower "internal version" of itself.
"internal version" is ivMAJOR.ivMINOR.ivBUILD with max values 255.255.65535.
Using the build nr allows continuous integration of the installer.
"Display version" is indipendent and free format: Year.Month.Bugfix as in Salt 2016.11.3.
Calculation of the internal version fields:
ivMAJOR = 'short year' (2 digits).
ivMINOR = 20*(month-1) + Bugfix
Combine Month and Bugfix to free ivBUILD for the build number
This limits Bugfix < 20.
The msi automatically replaces only 19 bugfixes of a month, one must uninstall manually.
ivBUILD = git commit count (noc)
noc for tags is 0, representing the final word, translates to the highest build number (65535).
Examples:
git checkout Display version Internal version Remark

2016.11 2016.11.2-78 16.202.78
