+files (example) and generates the C++ compatible C source code.  That code can
+be used to serialize the native C structures into compact and unambiguous
+BER/XER/PER-based data files, and deserialize the files back.
+
+Various ASN.1 based formats are widely used in the industry, such as to encode
+the X.509 certificates employed in the HTTPS handshake, to exchange control
+data between mobile phones and cellular networks, to car-to-car communication
+in intelligent transportation networks.
+
+The ASN.1 standard is large and complex and no open source compiler supports
+it in its entirety.  The asn1c is arguably the most evolved open source ASN.1
+compiler.")
