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

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

   300 Defaults for the options are specified in brackets.

   302 Configuration:

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

   304       --force             force configure to continue, even in case

   305                           some pre-requisites are missing

   307 Installation directories:

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

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

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

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

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

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

   316 For better control, use the options below.

   318 Fine tuning of the installation directories:

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

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

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

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

   324 Optional Features:

   325   --with-install=PATH     Specify the full PATH to GNU install

   326   --with-make=PATH        Specify the full PATH to GNU make >= 3.80

   327   --with-grep=PATH        Specify the full PATH to GNU grep

   328   --with-sed=PATH         Specify the full PATH to GNU sed

   329   --with-bash=PATH        Specify the full PATH to bash >= 3.0
