  * \def MBEDTLS_SSL_CONTEXT_SERIALIZATION
  *
- * Enable the APIs for serialization of a full SSL context:
- * mbedtls_ssl_context_save() and mbedtls_ssl_context_load().
+ * Enable serialization of the TLS context structures, through use of the
+ * functions mbedtls_ssl_context_save() and mbedtls_ssl_context_load().
  *
  * This pair of functions allows one side of a connection to serialize the
  * context associated with the connection, then free or re-use that context
  * while the serialized state is persisted elsewhere, and finally deserialize
  * that state to a live context for resuming read/write operations on the
- * connection, in a way that's transparent to the peer, since from a protocol
- * point of view, the state of the connection is unaffected.
