    \`configure' configures xkill 1.0.6 to adapt to many kinds of systems.
    
    Usage: $0 [OPTION]... [VAR=VALUE]...
    
    To assign environment variables (e.g., CC, CFLAGS...), specify them as
    VAR=VALUE.  See below for descriptions of some of the useful variables.
    
    Defaults for the options are specified in brackets.
    
    Configuration:
      -h, --help              display this help and exit
          --help=short        display options specific to this package
          --help=recursive    display the short help of all the included packages
      -V, --version           display version information and exit
      -q, --quiet, --silent   do not print \`checking ...' messages
          --cache-file=FILE   cache test results in FILE [disabled]
      -C, --config-cache      alias for \`--cache-file=config.cache'
      -n, --no-create         do not create output files
          --srcdir=DIR        find the sources in DIR [configure dir or \`..']
    
    Installation directories:
      --prefix=PREFIX         install architecture-independent files in PREFIX
                              [$ac_default_prefix]
      --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                              [PREFIX]
    
    By default, \`make install' will install all the files in
    \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
    an installation prefix other than \`$ac_default_prefix' using \`--prefix',
    for instance \`--prefix=\$HOME'.
    
    For better control, use the options below.

    Some influential environment variables:
      CC          C compiler command
      CFLAGS      C compiler flags
      LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
                  nonstandard directory <lib dir>
      LIBS        libraries to pass to the linker, e.g. -l<library>
      CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
                  you have headers in a nonstandard directory <include dir>
      CPP         C preprocessor
      PKG_CONFIG  path to pkg-config utility
      PKG_CONFIG_PATH
                  directories to add to pkg-config's search path
      PKG_CONFIG_LIBDIR
                  path overriding pkg-config's built-in search path
      XKILL_CFLAGS
                  C compiler flags for XKILL, overriding pkg-config
      XKILL_LIBS  linker flags for XKILL, overriding pkg-config
    
    Use these variables to override the choices made by `configure' or to help
    it to find libraries and programs with nonstandard names/locations.
