  25 # The code in this subdirectory is taken from Sun's RPCSRC-4.0
  26 # distribution with some additional changes from the TI-RPC package
  27 # which is also available from Sun.  The files are heavily changed to
  28 # compile cleanly and to fit in the GNU environment.  All the code
  29 # from Sun's rpc, etc, and rpcgen subdirectories is in this directory;
  30 # the rpc subdirectory contains only the header files.  Other than
  31 # that, several files were renamed so as not to exceed 14-character
  32 # file name limits:
