  "Description": "Build and use B-splines for interpolation and regression.\nIn case of regression, equality constraints as well as\nmonotonicity and/or positivity of B-spline weights can be\nimposed. Moreover, knot positions can be on regular grid or be\npart of optimized parameters too (in addition to the spline\nweights). For this end, 'bspline' is able to calculate Jacobian\nof basis vectors as function of knot positions. User is\nprovided with functions calculating spline values at arbitrary\npoints. These functions can be differentiated and integrated to\nobtain B-splines calculating derivatives/integrals at any\npoint. B-splines of this package can simultaneously operate on\na series of curves sharing the same set of knots. 'bspline' is\nwritten with concern about computing performance that's why the\nbasis and Jacobian calculation is implemented in C++. The rest\nis implemented in R but without notable impact on computing\nspeed.",
