* The encoding and decoding interface is simple. silc_asn1_encode is used
- * encode and silc_asn1_decode to decode. The actual ASN.1 is defined
+ * to encode and silc_asn1_decode to decode. The actual ASN.1 is defined
* as variable argument list to the function. Various macros can be used
* to encode and decode different ASN.1 types. All types may also be used
* to encode and decode with various options (such as implicit and explicit
* with SILC_ASN1_OPTS macro. Other options can be given with various
* SILC_ASN1_*_T macros.
*
+ * EXAMPLE
+ *
+ * // Encodes boolean value with explicit tag and private class, and
+ * // the result is allocated into `dest'.
+ * silc_asn1_encode(asn1, &dest,
