1912 \`configure' configures this package to adapt to many kinds of systems.

1914 Usage: $0 [OPTION]... [VAR=VALUE]...
1915
1916 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1917 VAR=VALUE.  See below for descriptions of some of the useful variables.
1918
1919 Defaults for the options are specified in brackets.
1920
1921 Configuration:
1922   -h, --help              display this help and exit
1923       --help=short        display options specific to this package
1924       --help=recursive    display the short help of all the included packages
1925   -V, --version           display version information and exit
1926   -q, --quiet, --silent   do not print \`checking...' messages
1927       --cache-file=FILE   cache test results in FILE [disabled]
1928   -C, --config-cache      alias for \`--cache-file=config.cache'
1929   -n, --no-create         do not create output files
1930       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

1932 Installation directories:
1933   --prefix=PREFIX         install architecture-independent files in PREFIX
1934                           [$ac_default_prefix]
1935   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1936                           [PREFIX]
1937
1938 By default, \`make install' will install all the files in
1939 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1940 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1941 for instance \`--prefix=\$HOME'.
1942
1943 For better control, use the options below.

1988   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1989   --enable-maintainer-mode  enable make rules and dependencies not useful
1990                           (and sometimes confusing) to the casual installer
1991   --disable-dependency-tracking  speeds up one-time build
1992   --enable-dependency-tracking   do not reject slow dependency extractors
1993
1994 Some influential environment variables:
1995   CC          C compiler command
1996   CFLAGS      C compiler flags
1997   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1998               nonstandard directory <lib dir>
1999   LIBS        libraries to pass to the linker, e.g. -l<library>
2000   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2001               you have headers in a nonstandard directory <include dir>
2002   CPP         C preprocessor
2003
2004 Use these variables to override the choices made by `configure' or to help
2005 it to find libraries and programs with nonstandard names/locations.
