1990 \`configure' configures this package to adapt to many kinds of systems.
1991
1992 Usage: $0 [OPTION]... [VAR=VALUE]...
1993
1994 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1995 VAR=VALUE.  See below for descriptions of some of the useful variables.
1996
1997 Defaults for the options are specified in brackets.
1998
1999 Configuration:
2000   -h, --help              display this help and exit
2001       --help=short        display options specific to this package
2002       --help=recursive    display the short help of all the included packages
2003   -V, --version           display version information and exit
2004   -q, --quiet, --silent   do not print \`checking...' messages
2005       --cache-file=FILE   cache test results in FILE [disabled]
2006   -C, --config-cache      alias for \`--cache-file=config.cache'
2007   -n, --no-create         do not create output files
2008       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2009
2010 Installation directories:
2011   --prefix=PREFIX         install architecture-independent files in PREFIX
2012                           [$ac_default_prefix]
2013   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2014                           [PREFIX]
2015
2016 By default, \`make install' will install all the files in
2017 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2018 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2019 for instance \`--prefix=\$HOME'.
2020
2021 For better control, use the options below.
2022
2023 Fine tuning of the installation directories:

2072 Some influential environment variables:
2073   CC          C compiler command
2074   CFLAGS      C compiler flags
2075   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2076               nonstandard directory <lib dir>
2077   LIBS        libraries to pass to the linker, e.g. -l<library>
2078   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2079               you have headers in a nonstandard directory <include dir>
2080   CPP         C preprocessor
2081
2082 Use these variables to override the choices made by `configure' or to help
2083 it to find libraries and programs with nonstandard names/locations.
