         Generate helper functions for named group
 
         It generates translation function from named group define to string.
-        Signature algorithm definition looks like:
+        Named group definition looks like:
         #define MBEDTLS_SSL_IANA_TLS_GROUP_[ upper case named group ] [ value(hex) ]
 
         Known limitation:
-        - the definitions SHOULD  exist in same macro blocks.
+        - the definitions SHOULD exist in same macro blocks.
