1226 \`configure' configures this package to adapt to many kinds of systems.
1227
1228 Usage: $0 [OPTION]... [VAR=VALUE]...
1229
1230 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1231 VAR=VALUE.  See below for descriptions of some of the useful variables.
1232
1233 Defaults for the options are specified in brackets.
1234
1235 Configuration:
1236   -h, --help              display this help and exit
1237       --help=short        display options specific to this package
1238       --help=recursive    display the short help of all the included packages
1239   -V, --version           display version information and exit
1240   -q, --quiet, --silent   do not print \`checking ...' messages
1241       --cache-file=FILE   cache test results in FILE [disabled]
1242   -C, --config-cache      alias for \`--cache-file=config.cache'
1243   -n, --no-create         do not create output files
1244       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1245
1246 Installation directories:
1247   --prefix=PREFIX         install architecture-independent files in PREFIX
1248                           [$ac_default_prefix]
1249   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1250                           [PREFIX]
1251
1252 By default, \`make install' will install all the files in
1253 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1254 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1255 for instance \`--prefix=\$HOME'.
1256
1257 For better control, use the options below.

1259 Fine tuning of the installation directories:
1260   --bindir=DIR            user executables [EPREFIX/bin]
1261   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1289 Optional Features:
1290   --disable-option-checking  ignore unrecognized --enable/--with options
1291   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
1292   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1293   --enable-plugin=pppd_src_path   build pppd plugin
1294   --disable-debugging             disable debugging code
1295   --enable-licenses=lic_path      build commercial version
1296
1297 Some influential environment variables:
1298   CC          C compiler command
1299   CFLAGS      C compiler flags
1300   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1301               nonstandard directory <lib dir>
1302   LIBS        libraries to pass to the linker, e.g. -l<library>
1303   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1304               you have headers in a nonstandard directory <include dir>
1305   CPP         C preprocessor
1306
1307 Use these variables to override the choices made by `configure' or to help
1308 it to find libraries and programs with nonstandard names/locations.
