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

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

    97 Defaults for the options are specified in brackets.

    99 Configuration:

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

   102 Installation directories:

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

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

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

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

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

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

   111 For better control, use the options below.

   113 Fine tuning of the installation directories:

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

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

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

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

   119 Optional Features:

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

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

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

   123                          'list' to see which are available.
