libjmmcg is a basic, low-level library with pretensions to implementing features above and beyond (but not necessarily better than!) those implemented within the Standard C++ Library and the Boost Library. It features a library for multi-core or multi-chip SMP parallelism, a suite of hashing algorithms, functions for raising numbers to integer powers, a generic factory wrapper and a generic, multi-threaded, read-only cache (which uses PPD), arguably the world's worst sorting technique, trace output, exceptions that have the file, line, revision, function, and argument details, string utilities, logging, simple command line processing, and much more.
cipra is a simple, TAP-compatible Unit Testing Framework for C++. It's written in 100% standard C++11 and is only a couple of header files, making it easy to include in your C++11 project. TAP, the Test Anything Protocol, is a standard output format for software unit test frameworks which was originally designed for Perl, but can serve other languages. It has a rich number of tools ("harnesses") which parse TAP-formatted output and do useful things with it. TAP, however, is equally human-readable. The name cipra (pronounced /ˈʃi.pɾaː/ "SHEE-prah") comes from the lojban phrase "lo cipra", which means "the test". It is properly written with an initial minuscule "c", even when at the start of a sentence.
OOS is a C++ object-relational mapping (ORM) framework. It aims to encapsulate all of the database backend functionality and keep it away from the user. One don't have to deal with database backends or SQL statements, nor with mapping of data types or serialization of objects. It provides an STL-like API and one container for all persistent objects - the object store.
