+Program properties are used to record information about an object file or binary
+that a linker or runtime loader needs to check for compatibility.
 
-The program property is divided into different classes, each defining a range
-of program property types and specifying the merge semantics. This is designed
-for forward compatibility in linker implementations, allowing them to correctly
-handle program property types even if they are not recognized.
