%description
Interface to the 'sTiles' framework for tile-based sparse Cholesky
factorization: log-determinants, selected inverse (marginal variances) and
triangular solves, with symbolic reuse so that repeated factorization of
matrices sharing one sparsity pattern pays the ordering cost only once, as
in a hyperparameter sweep. The compiled glue in this package resolves its
symbols at run time against the 'sTiles' solver library ('libstiles'),
which is a separate component distributed under its own terms and is not
part of this package. Install it once with 'sTiles_install_library()', or
point the package at a copy you already have with the 'STILES_LIB'
environment variable.
