1210 \`configure' configures secnet 0.1.16+ to adapt to many kinds of systems.
1211
1212 Usage: $0 [OPTION]... [VAR=VALUE]...
1213
1214 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1215 VAR=VALUE.  See below for descriptions of some of the useful variables.
1216
1217 Defaults for the options are specified in brackets.
1218
1219 Configuration:
1220   -h, --help              display this help and exit
1221       --help=short        display options specific to this package
1222       --help=recursive    display the short help of all the included packages
1223   -V, --version           display version information and exit
1224   -q, --quiet, --silent   do not print \`checking ...' messages
1225       --cache-file=FILE   cache test results in FILE [disabled]
1226   -C, --config-cache      alias for \`--cache-file=config.cache'
1227   -n, --no-create         do not create output files
1228       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1229
1230 Installation directories:
1231   --prefix=PREFIX         install architecture-independent files in PREFIX
1232                           [$ac_default_prefix]
1233   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1234                           [PREFIX]
1235
1236 By default, \`make install' will install all the files in
1237 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1238 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1239 for instance \`--prefix=\$HOME'.
1240
1241 For better control, use the options below.

1281 Some influential environment variables:
1282   CC          C compiler command
1283   CFLAGS      C compiler flags
1284   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1285               nonstandard directory <lib dir>
1286   LIBS        libraries to pass to the linker, e.g. -l<library>
1287   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1288               you have headers in a nonstandard directory <include dir>
1289   CPP         C preprocessor
1290
1291 Use these variables to override the choices made by `configure' or to help
1292 it to find libraries and programs with nonstandard names/locations.
