Aesop is a high-performance, high-productivity language designed to simplify the design and implementation of highly concurrent services.
Aesop is implemented as a source-to-source translator which translates the aesop language (C + some extensions for concurrency and cancellation) to C99-compatible code, which then can be compiled by a suitable C compiler.
Currently, Aesop is mainly used to implement Triton, a highly scalable storage system.
