1248 \`configure' configures secnet 0.1.18+ to adapt to many kinds of systems.
1249
1250 Usage: $0 [OPTION]... [VAR=VALUE]...
1251
1252 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1253 VAR=VALUE.  See below for descriptions of some of the useful variables.
1254
1255 Defaults for the options are specified in brackets.
1256
1257 Configuration:
1258   -h, --help              display this help and exit
1259       --help=short        display options specific to this package
1260       --help=recursive    display the short help of all the included packages
1261   -V, --version           display version information and exit
1262   -q, --quiet, --silent   do not print \`checking ...' messages
1263       --cache-file=FILE   cache test results in FILE [disabled]
1264   -C, --config-cache      alias for \`--cache-file=config.cache'
1265   -n, --no-create         do not create output files
1266       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1267
1268 Installation directories:
1269   --prefix=PREFIX         install architecture-independent files in PREFIX
1270                           [$ac_default_prefix]
1271   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1272                           [PREFIX]
1273
1274 By default, \`make install' will install all the files in
1275 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1276 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1277 for instance \`--prefix=\$HOME'.
1278
1279 For better control, use the options below.

1281 Fine tuning of the installation directories:
1282   --bindir=DIR            user executables [EPREFIX/bin]
1283   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1320 Some influential environment variables:
1321   CC          C compiler command
1322   CFLAGS      C compiler flags
1323   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1324               nonstandard directory <lib dir>
1325   LIBS        libraries to pass to the linker, e.g. -l<library>
1326   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1327               you have headers in a nonstandard directory <include dir>
1328   CPP         C preprocessor
1329
1330 Use these variables to override the choices made by `configure' or to help
1331 it to find libraries and programs with nonstandard names/locations.
