%description
Bundles the pure-C part of the 'SUNDIALS' suite (CVODE, CVODES, ARKODE,
IDA, IDAS and KINSOL with the serial vector and the dense, band and
iterative linear solvers) and builds it into a static library. Other
packages use it by adding 'sundials' to 'LinkingTo' for the headers and
calling sundials::LdFlags() from their 'Makevars' to link the library. No
'Fortran', 'MPI', GPU or external third-party-library modules are
included. 'SUNDIALS' is described in Hindmarsh et al. (2005)
<doi:10.1145/1089014.1089020>.
