+Sdb
+
+Sdb files are Shim Databases.
+They contain information about bad applications, and about the fixes that can be applied to them.
+
+
+Shims
+
+A shim is a piece of code that influences the process it's applied to.
+This can be done by calling certain api's, or by changing the behavior of api's.
+'DisableThemes' is an example of a shim that changes behavior by calling 'SetThemeAppProperties'.
+'Win95VersionLie' is an example of a shim that changes behavior, by intercepting calls to GetVersion[Ex].
+
+Layers
+
+A layer is a collection (1..n) of shims.
+Layers are used to reference a collection of shims by name.
