The source code is organized by subdirectories:

include: Headers describing the official API. Headers in other places are for internal use only.

arith: Finite fields: modular arithmetic, polynomial rings, and polynomial rings modulo a polynomial. Finite fields of low characteristic are unsupported.

ecc: Elliptic curve generation, elliptic curve groups and pairings. One source file is dedicated to each type of pairing, containing specialized optimizations. Some of the code requires arbitrary precision complex numbers, which also live here but should be moved elsewhere one day.

misc: Dynamic arrays, symbol tables, benchmarking, logging, debugging, other utilities.

gen: Programs that generate pairing parameters and list Hilbert polynomials. These were used to prepare the samples in the param directory.

example: Example programs showing how to use the library.

guru: Tests, experimental code.
