  "Description": "Interface to the 'sTiles' framework for tile-based sparse\nCholesky factorization: log-determinants, selected inverse\n(marginal variances) and triangular solves, with symbolic reuse\nso that repeated factorization of matrices sharing one sparsity\npattern pays the ordering cost only once, as in a\nhyperparameter sweep. The compiled glue in this package\nresolves its symbols at run time against the 'sTiles' solver\nlibrary ('libstiles'), which is a separate component\ndistributed under its own terms and is not part of this\npackage. Install it once with 'sTiles_install_library()', or\npoint the package at a copy you already have with the\n'STILES_LIB' environment variable.",
