" DESCRIPTION: \n"
" \n"
" Server-side of the test program for IPv4Socket class. Tests \n"
" basic types XDR-encoded transmission. They are: \n"
" CHAR, SHORT, INT, UINT, LONG, ULONG, FLOAT, DOUBLE. \n"
" See client-side is 'echoxdr_testc' for further details. \n"
" \n"
" USAGE: \n"
" \n"
" shell> echoxdr_tests [OPTIONS] \n"
" \n"
" OPTIONS: \n"
" \n"
" -b, --daemon - run process as true UNIX daemon \n"
" -d, --log-stdout - write debug to standard output \n"
" -D, --log-file NAME - write debug to NAME file \n"
" -h, --help - print this message \n"
" -m, --mask MASK - mask (default: ALL = 0x7fffffff) \n"
" -p, --port NAME - tcp/ip port NAME (default - procname) \n"
" -v, --version - print version number \n"
" -z, --log-size NUM - maximum size debug file can reach (dflt: 10Mb) \n"
