 .SH DESCRIPTION
-asn1c is a tool to compile the ASN.1 specifications into C language structures
-and accompanying routines to perform data encoding and decoding.
+asn1c compiles the ASN.1 specifications into the set of
+target language (C/C++) encoders and decoders for BER, DER,
+and other encoding standards.
