     9 #  - awk must be GNU awk

    10 #  - makeinfo for building docs, even if discarded later on

    13 # Format of a pattern to check for, one per line:

    14 #   pattern := tool_test  OR  pattern|tool_test

    15 #   tool_test := tool/regexp

    16 #   tool := name of the tool  OR  absolute pathname to the tool

    17 #   regexp := valid grep(1) extended regular expression  OR  empty

    18 #

    19 # In case a pattern list is given (eg foo|bar|buz), then tests are performed

    20 # from left to right, stopping at the first matching test (like the shell

    21 # would parse 'foo || bar || buz' ).

    22 #

    23 # Examples:

    24 #    /bin/bash/^GNU bash, version 3\.

    25 #       will ensure that /bin/bash exists, and that $(/bin/bash --version)

    26 #       matches the regexp '^GNU bash, version 3\.'

    27 #    autoconf/(GNU Autoconf)|autoconf2.50/

    28 #       will ensure that:

    29 #         - 'autoconf' is to be found in the PATH, and that $(autoconf

    30 #           --version) matches the regexp '(GNU Autoconf)' (which btw is

    31 #           the signature of autoconf >= 2.50),

    32 #       OR that:

   179 \`configure' configures crosstool-NG ${VERSION} to adapt to many kind of systems.

   181 USAGE: ./configure [OPTION]...

   183 Defaults for the options are specified in brackets.

   185 Configuration:

   186   -h, --help              display this help and exit

   187       --force             force ./configure to complete, even if one or more

   188                           tools were not found. Use at your own risk, only if

   189                           you know what you are doing!

   191 Installation directories:

   192   --prefix=PREFIX         install files in PREFIX [${PREFIX_DEFAULT}]

   193   --local                 don't install, and use current directory

   195 By default, \`make install' will install all the files in

   196 \`${PREFIX_DEFAULT}/bin', \`${PREFIX_DEFAULT}/lib' etc.  You can specify

   197 an installation prefix other than \`${PREFIX_DEFAULT}' using \`--prefix',

   198 for instance \`--prefix=\${HOME}'.

   200 For better control, use the options below.

   202 Fine tuning of the installation directories:

   203   --bindir=DIR            user executables [PREFIX/bin]

   204   --libdir=DIR            object code libraries [PREFIX/lib]

   205   --docdir=DIR            info documentation [PREFIX/share/doc]

   206   --mandir=DIR            man documentation [PREFIX/share/man]

   208 Optional Features:

   209   --with-contrib=XXX      Include externally contributed features found in the

   210                           contrib/ sub-directory. Set to a comma-separated list

   211                           of features. Use 'all' to use all contributions, and

   212                           'list' to see which are available.
