摘要：
Encoding a new version of a data module includes constructing a delta data module having data for providing the new version of the data module. The delta data module may indicate an encoding for copying data at an offset from one of a number of pointers into different versions of the data module. Decoding a delta data module to provide a new version of a data module includes copying, to the new version of the data module, data relative to a target pointer when an encoding in the delta data module indicates a matching pattern relative to the target pointer, and copying, to the new version of the data module, data relative to at least one other pointer when an encoding in the delta data module indicates a matching pattern relative to the at least one other pointer.
