*
* DESCRIPTION
*
- * Simple implementation of MIME. Supports creation and parsing of simple
+ * Simple MIME Interface. This API supports creation and parsing of simple
* MIME messages, multipart MIME messages, including nested multiparts, and
* MIME fragmentation and defragmentation.
*
+ * SILC Mime API is not thread-safe. If the same SilcMime context must be
+ * used in multithreaded environment concurrency control must be employed.
