+/**
+ * @file Intention of this little module: exif.module needs to have a weight of -10
+ * at least it has to be processed before CCK is processed, so that EXIF information
+ * can be taken from the fields and be written into the CCK fields.
+ *
+ * Problem: We don't want to display the emty fields on node creation, since they are
+ * reserved for exif information -> we don't want to confuse users with this, so are
+ * going to make them hidden -> Information needs to be processed AFTER CCK.
+ *
+ * Solution: Creating a new little module.
