615Usage: $0 [OPTION]... [VAR=VALUE]...
616
617To assign environment variables (e.g., CC, CFLAGS...), specify them as
618VAR=VALUE.  See below for descriptions of some of the useful variables.
619
620Defaults for the options are specified in brackets.
621
622Configuration:
623  -h, --help              display this help and exit
624      --help=short        display options specific to this package
625      --help=recursive    display the short help of all the included packages
626  -V, --version           display version information and exit
627  -q, --quiet, --silent   do not print \`checking...' messages
628      --cache-file=FILE   cache test results in FILE [disabled]
629  -C, --config-cache      alias for \`--cache-file=config.cache'
630  -n, --no-create         do not create output files

642By default, \`make install' will install all the files in
643\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
644an installation prefix other than \`$ac_default_prefix' using \`--prefix',
645for instance \`--prefix=\$HOME'.

702Some influential environment variables:
703  CC          C compiler command
704  CFLAGS      C compiler flags
705  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
706              nonstandard directory <lib dir>
707  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
708              headers in a nonstandard directory <include dir>
709  CPP         C preprocessor
710
711Use these variables to override the choices made by `configure' or to help
712it to find libraries and programs with nonstandard names/locations.
