+// Package core is the core of the IRMA server library, allowing IRMA verifiers, issuers
+// or attribute-based signature applications to perform IRMA sessions with irmaclient instances
+// (i.e. the IRMA app). It exposes a small interface to expose to other programming languages
+// through cgo. It is used by the irmarequestor package but otherwise not meant for use in Go.
