+ * Minimal configuration for TLS 1.2 with PSK and AES-CCM ciphersuites
+ * Distinguishing features:
+ * - no bignum, no PK, no X509
+ * - fully modern and secure (provided the pre-shared keys have high entropy)
+ * - very low record overhead with CCM-8
+ * - optimized for low RAM usage
+ *
+ * See README.txt for usage instructions.
