TREXIO source code documentation

TREXIO is an open-source file format and library developed for the storage and manipulation of data produced by quantum chemistry calculations. It was designed with the goal of providing a reliable and efficient method of storing and exchanging wave function parameters and matrix elements.

The library consists of a front-end implemented in the C programming language and two different back-ends: a text back-end and a binary back-end utilizing the HDF5 library enabling fast read and write speeds. It is compatible with a variety of platforms and has interfaces for Fortran, Python, and OCaml.
