Athena is a small library that provides powerful, cross platform, endian independent IO. It has the ability to automatically detect the endian the system is on, even it's a mixed endian system, and behave appropriately. It also provides a few classes for Nintendo specific formats, such as data.bin, ALTTP SRAM, Yaz0 encoding, LZ77 (LZ10, and LZ11) and a few others.
