# The code in this subdirectory is taken from Sun's RPCSRC-4.0

# distribution with some additional changes from the TI-RPC package

# which is also available from Sun.  The files are heavily changed to

# compile cleanly and to fit in the GNU environment.  All the code

# from Sun's rpc, etc, and rpcgen subdirectories is in this directory;

# the rpc subdirectory contains only the header files.  Other than

# that, several files were renamed so as not to exceed 14-character

# file name limits:

#

#	authunix_prot.c -> authuxprot.c

#	bindresvport.c -> bindrsvprt.c

#	clnt_generic.c -> clnt_gen.c

#	clnt_perror.c -> clnt_perr.c

#	clnt_simple.c -> clnt_simp.c

#	get_myaddress.c -> get_myaddr.c
