1303Usage: $0 [OPTION]... [VAR=VALUE]...
1304
1305To assign environment variables (e.g., CC, CFLAGS...), specify them as
1306VAR=VALUE.  See below for descriptions of some of the useful variables.
1307
1308Defaults for the options are specified in brackets.
1309
1310Configuration:
1311  -h, --help              display this help and exit
1312      --help=short        display options specific to this package
1313      --help=recursive    display the short help of all the included packages
1314  -V, --version           display version information and exit
1315  -q, --quiet, --silent   do not print \`checking ...' messages
1316      --cache-file=FILE   cache test results in FILE [disabled]
1317  -C, --config-cache      alias for \`--cache-file=config.cache'
1318  -n, --no-create         do not create output files
1319      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1320
1321Installation directories:
1322  --prefix=PREFIX         install architecture-independent files in PREFIX
1323                          [$ac_default_prefix]
1324  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1325                          [PREFIX]
1326
1327By default, \`make install' will install all the files in
1328\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1329an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1330for instance \`--prefix=\$HOME'.

1404  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1405              nonstandard directory <lib dir>
1406  LIBS        libraries to pass to the linker, e.g. -l<library>
1407  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

2847Oops!
2848
2849Your 'rm' program seems unable to run without file operands specified
2850on the command line, even when the '-f' option is present.  This is contrary
2851to the behaviour of most rm programs out there, and not conforming with
2852the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
2853
2854Please tell bug-automake@gnu.org about your system, including the value
2855of your $PATH and any error possibly output before this message.  This
2856can help us improve future automake versions.
