manostool --init dies ungracefully if no AppName is given

[dwierenga]

When running manostool.exe --init, the application dies with a stacktrace if no AppName is given:

.\manostool.exe --init
manos --init
This will initialize a new application with the supplied name.
error while initializing application:
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

However the ShowHelp mentions nothing about needing an argument:

./manostool -h init
