   1 #
   2 #  This code depends on heimdal's asn1_compile generated krb5 decoding
   3 #  stuff. The code is originally from rxkad that Björn Grönvall
   4 #  <bg@sics.se> for kth-krb and was included in Arla.
   5 #
   6 #  The first file, v5der.c are part for of support functions
   7 #  that all generated files depends on.
   8 #
   9 #  The second file (v5gen.h) is the header file that is generated for
  10 #  the decoding functions.
  11 #
  12 #  The third file (v5gen.c) is the subset of the generated functions we
  13 #  need to decode the authenticator.
  14 #
  15 #  The forth file (v5gen-rewrite.h) is used to make sure we don't
  16 #  pollute the namespace.
  17 #
  18 #  All files are modified to build within OpenAFS environment without
  19 #  any external dependencies. Below is the shell script that is used to
  20 #  import the code into the four files.
  21 #
  22 #  All internal symbols are rewritten to _rxkad_v5_.
  23 #
  24
  25 # Make sure we don't export too much
