1532 \`configure' configures this package to adapt to many kinds of systems.
1533
1534 Usage: $0 [OPTION]... [VAR=VALUE]...
1535
1536 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1537 VAR=VALUE.  See below for descriptions of some of the useful variables.
1538
1539 Defaults for the options are specified in brackets.
1540
1541 Configuration:
1542   -h, --help              display this help and exit
1543       --help=short        display options specific to this package
1544       --help=recursive    display the short help of all the included packages
1545   -V, --version           display version information and exit
1546   -q, --quiet, --silent   do not print \`checking...' messages
1547       --cache-file=FILE   cache test results in FILE [disabled]
1548   -C, --config-cache      alias for \`--cache-file=config.cache'
1549   -n, --no-create         do not create output files
1550       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1551
1552 Installation directories:
1553   --prefix=PREFIX         install architecture-independent files in PREFIX
1554                           [$ac_default_prefix]
1555   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1556                           [PREFIX]
1557
1558 By default, \`make install' will install all the files in
1559 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1560 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1561 for instance \`--prefix=\$HOME'.
1562
1563 For better control, use the options below.
1564
1565 Fine tuning of the installation directories:
1566   --bindir=DIR            user executables [EPREFIX/bin]
1567   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1568   --libexecdir=DIR        program executables [EPREFIX/libexec]
1569   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1570   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
1571   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
1572   --libdir=DIR            object code libraries [EPREFIX/lib]
1573   --includedir=DIR        C header files [PREFIX/include]
1574   --oldincludedir=DIR     C header files for non-gcc [/usr/include]
1575   --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
1576   --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
1577   --infodir=DIR           info documentation [DATAROOTDIR/info]

1589 Program names:

1591   --program-suffix=SUFFIX            append SUFFIX to installed program names
1592   --program-transform-name=PROGRAM   run sed PROGRAM on installed program names
1593
1594 System types:
1595   --build=BUILD     configure for building on BUILD [guessed]
1596   --host=HOST       cross-compile to build programs to run on HOST [BUILD]

1605 Optional Features:
1606   --disable-option-checking  ignore unrecognized --enable/--with options
1607   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
1608   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1609   --enable-maintainer-mode  enable make rules and dependencies not useful
1610                           (and sometimes confusing) to the casual installer
1611   --disable-dependency-tracking  speeds up one-time build
1612   --enable-dependency-tracking   do not reject slow dependency extractors
1613
1614 Some influential environment variables:
1615   CC          C compiler command
1616   CFLAGS      C compiler flags
1617   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1618               nonstandard directory <lib dir>
1619   LIBS        libraries to pass to the linker, e.g. -l<library>
1620   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1621               you have headers in a nonstandard directory <include dir>
1622   CPP         C preprocessor
1623
1624 Use these variables to override the choices made by `configure' or to help
1625 it to find libraries and programs with nonstandard names/locations.
