esnacc is short for "Enhanced Sample Neufeld ASN.1 to C Compiler" and ASN.1
 stands for Abstract Syntax Notation One (ITU-T X.208/ISO 8824).
 esnacc supports a subset of ASN.1 1988.
 .
 Given an ASN.1 source file(s) esnacc can produce:
 .
 1. C routines for BER encoding, decoding, printing and freeing.
 2. C++ routines for BER encoding, decoding, and printing.
 3. A type table that can be used with C driver routines
    for BER encoding, decoding, printing and freeing.
 .
 If you want to build esnacc based applications, you want to install
 the libesnacc-dev package, too. Your application will then depend on
 the esnacc libraries, you find in the libesnacc180 package.
