snacc
    (Sample Neufeld ASN.1 to C/C++ Compiler) A program
   by Mike Sample  which compiles 1990
   ASN.1 data structures (including some macros) into C,
   C++ or type tables.  The generated C/C++ includes a .h
   file with the equivalent data struct and a .c/.C file for the
   BER encode and decode, print and free routines.
   snacc includes the compiler, run-time BER libraries, and
   utility programs.  snacc is compiled under GNU General
   Public License.  It requires yacc or bison, lex or
   flex, and cc (ANSI or non-ANSI).
