1786 \`configure' configures this package to adapt to many kinds of systems.
1787
1788 Usage: $0 [OPTION]... [VAR=VALUE]...
1789
1790 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1791 VAR=VALUE.  See below for descriptions of some of the useful variables.
1792
1793 Defaults for the options are specified in brackets.
1794
1795 Configuration:
1796   -h, --help              display this help and exit
1797       --help=short        display options specific to this package
1798       --help=recursive    display the short help of all the included packages
1799   -V, --version           display version information and exit
1800   -q, --quiet, --silent   do not print \`checking...' messages
1801       --cache-file=FILE   cache test results in FILE [disabled]
1802   -C, --config-cache      alias for \`--cache-file=config.cache'
1803   -n, --no-create         do not create output files
1804       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1805
1806 Installation directories:
1807   --prefix=PREFIX         install architecture-independent files in PREFIX
1808                           [$ac_default_prefix]
1809   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1810                           [PREFIX]
1811
1812 By default, \`make install' will install all the files in
1813 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1814 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1815 for instance \`--prefix=\$HOME'.
1816
1817 For better control, use the options below.

1819 Fine tuning of the installation directories:
1820   --bindir=DIR            user executables [EPREFIX/bin]

1861   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
1862   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1863   --enable-maintainer-mode  enable make rules and dependencies not useful
1864                           (and sometimes confusing) to the casual installer
1865   --disable-dependency-tracking  speeds up one-time build
1866   --enable-dependency-tracking   do not reject slow dependency extractors
1867
1868 Some influential environment variables:
1869   CC          C compiler command
1870   CFLAGS      C compiler flags
1871   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1872               nonstandard directory <lib dir>
1873   LIBS        libraries to pass to the linker, e.g. -l<library>
1874   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1875               you have headers in a nonstandard directory <include dir>
1876   CPP         C preprocessor
1877
1878 Use these variables to override the choices made by `configure' or to help
1879 it to find libraries and programs with nonstandard names/locations.
