\`configure' configures crosstool-NG ${VERSION} to adapt to many kind of systems.
USAGE: ./configure [OPTION]...
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--prefix=PREFIX install files in PREFIX [${PREFIX_DEFAULT}]
--local don't install, and use current directory
By default, \`make install' will install all the files in
\`${PREFIX_DEFAULT}/bin', \`${PREFIX_DEFAULT}/lib' etc. You can specify
an installation prefix other than \`${PREFIX_DEFAULT}' using \`--prefix',
for instance \`--prefix=\${HOME}'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [PREFIX/bin]
--libdir=DIR object code libraries [PREFIX/lib]
--docdir=DIR info documentation [PREFIX/share/doc]
--mandir=DIR man documentation [PREFIX/share/man]
Optional Features:
--with-contrib=XXX Include externally contributed features found in the
contrib/ sub-directory. Set to a comma-separated list
of features. Use 'all' to use all contributions, and
'list' to see which are available.
