1526 \`configure' configures this package to adapt to many kinds of systems.

1528 Usage: $0 [OPTION]... [VAR=VALUE]...
1529
1530 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1531 VAR=VALUE.  See below for descriptions of some of the useful variables.
1532
1533 Defaults for the options are specified in brackets.
1534
1535 Configuration:
1536   -h, --help              display this help and exit
1537       --help=short        display options specific to this package
1538       --help=recursive    display the short help of all the included packages
1539   -V, --version           display version information and exit
1540   -q, --quiet, --silent   do not print \`checking...' messages
1541       --cache-file=FILE   cache test results in FILE [disabled]
1542   -C, --config-cache      alias for \`--cache-file=config.cache'
1543   -n, --no-create         do not create output files
1544       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1545
1546 Installation directories:
1547   --prefix=PREFIX         install architecture-independent files in PREFIX
1548                           [$ac_default_prefix]
1549   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1550                           [PREFIX]
1551
1552 By default, \`make install' will install all the files in
1553 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1554 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1555 for instance \`--prefix=\$HOME'.

1771   CC          C compiler command
1772   CFLAGS      C compiler flags
1773   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1774               nonstandard directory <lib dir>
1775   LIBS        libraries to pass to the linker, e.g. -l<library>
1776   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1777               you have headers in a nonstandard directory <include dir>
1778   CXX         C++ compiler command
1779   CXXFLAGS    C++ compiler flags
1780   CXXCPP      C++ preprocessor
1781   CPP         C preprocessor
1782   GMPLIBS     How to link GMP
