CCTZ contains two libraries that cooperate with `<chrono>` to give C++ programmers all the necessary tools for computing with dates, times, and time zones in a simple and correct manner.

Library needed for GNU Go applications linked against the shared library.

GNU Transactional Memory Library (libitm) provides transaction support for accesses to the memory of a process, enabling easy-to-use synchronization of accesses to shared memory by several threads.

UndefinedBehaviorSanitizer can be enabled via -fsanitize=undefined. Various computations will be instrumented to detect undefined behavior at runtime. Available for C and C++.

Libcifpp is a C++ library used to create and manipulate mmCIF and PDB files containing macro molecular structure information.

mbed TLS (formerly known as PolarSSL) is a lean open source crypto library for providing SSL and TLS support in your programs. It offers an intuitive API and documented header files, so you can actually understand what the code does. It features: - Symmetric algorithms, like AES, Blowfish, Triple-DES, DES, ARC4, Camellia and XTEA - Hash algorithms, like SHA-1, SHA-2, RIPEMD-160 and MD5 - Entropy pool and random generators, like CTR-DRBG and HMAC-DRBG - Public key algorithms, like RSA, Elliptic Curves, Diffie-Hellman, ECDSA and ECDH - TLS 1.0, 1.1 and 1.2 - Abstraction layers for ciphers, hashes, public key operations, platform abstraction and threading
