+// Package scram provides client and server implementations of the Salted
+// Challenge Response Authentication Mechanism (SCRAM) described in RFC-5802
+// and RFC-7677.
+//
+// Usage
+//
+// The scram package provides variables, `SHA1`, `SHA256`, and `SHA512`, that
+// are used to construct Client or Server objects.
+//
+//     clientSHA1,   err := scram.SHA1.NewClient(username, password, authID)
+//     clientSHA256, err := scram.SHA256.NewClient(username, password, authID)
+//     clientSHA512, err := scram.SHA512.NewClient(username, password, authID)
+//
+//     serverSHA1,   err := scram.SHA1.NewServer(credentialLookupFcn)
+//     serverSHA256, err := scram.SHA256.NewServer(credentialLookupFcn)
+//     serverSHA512, err := scram.SHA512.NewServer(credentialLookupFcn)
+//
+// These objects are used to construct ClientConversation or
+// ServerConversation objects that are used to carry out authentication.
