This project is a line-by-line C translation of the reference LAPACK. Because we control the LAPACK layer code, our only external dependency is the ~150 CBLAS functions interface. This drastically reduces the ABI surface compared to projects wrapping vendor Fortran LAPACK, and makes LP64/ILP64 support a clean dual build without symbol mangling. In practice, this means a full BLAS/LAPACK stack that needs only a C compiler. For example, one can build OpenBLAS with only its CBLAS option and link it against this project, and you have a complete LAPACK stack built entirely with a C compiler.
