mms (memory-mapped storage) is a library capable of serializing quite complex data in a way that the serialized data can be mmap()-ped and used without any additional time or memory consumption with the well-known STL-like interface.

A short example of its usage can be found in example.cpp (compiles with "g++ -std=gnu++11 -Iinclude example.cpp").
