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

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

   155 Defaults for the options are specified in brackets.

   157 Configuration:

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

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

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

   161                           you know what you are doing!

   163 Installation directories:

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

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

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

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

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

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

   172 For better control, use the options below.

   174 Fine tuning of the installation directories:

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

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

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

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

   180 Optional Features:

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

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

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

   184                           'list' to see which are available.
