// Package pkg defines CUE standard packages.
//
// Many of the standard packages are modeled after and generated from the Go
// core packages. The types, values, and functions are defined as their Go
// equivalence and mapped to CUE types.
//
// Beware that some packages are defined in lesser-precision types than are
// typically used in CUE and thus may lead to loss of precision.
//
// All packages except those defined in the tool subdirectory are hermetic,
// that is depending only on a known set of inputs, and therefore can guarantee
// reproducible results.  That is:
//
//   - no reading of files contents
//   - no querying of the file system of any kind
//   - no communication on the network
//   - no information about the type of environment
//   - only reproducible random generators
//
// Hermetic configurations allow for fast and advanced analysis that otherwise
// would not be possible or practical. The cue "cmd" command can be used to mix
// in non-hermetic influences into configurations by using packages defined
// in the tool subdirectory.
