The EXP-T program package is designed for high-precision modeling of molecular electronic structure using the relativistic Fock space multireference coupled cluster method (FS-RCC). EXP-T is written from scratch in the C99 programming language and is currently focused on Unix-like systems.

The public version of the EXP-T source code is available under LGPLv3.
EXP-T uses some external libraries as a part of its source code.
The OpenBLAS library v0.3.10 is used as an internal implementation of BLAS/LAPACK; see https://www.openblas.net/.
The LZ4 library v1.9.0 is used in the I/O subsystem for data compression; see https://github.com/lz4/lz4
