1185 \`configure' configures this package to adapt to many kinds of systems.
1186
1187 Usage: $0 [OPTION]... [VAR=VALUE]...
1188
1189 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1190 VAR=VALUE.  See below for descriptions of some of the useful variables.
1191
1192 Defaults for the options are specified in brackets.
1193
1194 Configuration:
1195   -h, --help              display this help and exit
1196       --help=short        display options specific to this package
1197       --help=recursive    display the short help of all the included packages
1198   -V, --version           display version information and exit
1199   -q, --quiet, --silent   do not print \`checking ...' messages
1200       --cache-file=FILE   cache test results in FILE [disabled]
1201   -C, --config-cache      alias for \`--cache-file=config.cache'
1202   -n, --no-create         do not create output files
1203       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1204
1205 Installation directories:
1206   --prefix=PREFIX         install architecture-independent files in PREFIX
1207                           [$ac_default_prefix]
1208   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1209                           [PREFIX]
1210
1211 By default, \`make install' will install all the files in
1212 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1213 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1214 for instance \`--prefix=\$HOME'.
1215
1216 For better control, use the options below.

1219   --bindir=DIR            user executables [EPREFIX/bin]
