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