MGR.Guard.Sources
The purpose of the MGR.Guard.Sources package is to provide the MGR.Guard
library as source code to be used in a library without adding a
dependency to it.
All classes (MGR.Guard.Guardian, MGR.Guard.GuardianExtensions and the now obsolete MGR.Guard.Guard) are marked as internal to not be exposed by your library.
These classes can be marked as public by setting the constant MGR_GUARD_PUBLIC.
