-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-			  [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-			  [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR           user executables [EPREFIX/bin]
-  --sbindir=DIR          system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR       program executables [EPREFIX/libexec]
-  --datadir=DIR          read-only architecture-independent data [PREFIX/share]

-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

-  CPP         C preprocessor

-    #	1. Use "connect" and "accept" to check for -lsocket, and

-    #	2. Use each function name only once:  can't redo a check because

-    #	3. Use -lnsl and -lsocket only if they supply procedures that
-    #	   aren't already present in the normal libraries.  This is because
-    #	   IRIX 5.2 has libraries, but they aren't needed and they're
-    #	   bogus:  they goof up name resolution if used.
-    #	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
-    #	   To get around this problem, check for both libraries together
