1237 \`configure' configures secnet 0.1.18+ to adapt to many kinds of systems.
1238
1239 Usage: $0 [OPTION]... [VAR=VALUE]...
1240
1241 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1242 VAR=VALUE.  See below for descriptions of some of the useful variables.
1243
1244 Defaults for the options are specified in brackets.
1245
1246 Configuration:
1247   -h, --help              display this help and exit
1248       --help=short        display options specific to this package
1249       --help=recursive    display the short help of all the included packages
1250   -V, --version           display version information and exit
1251   -q, --quiet, --silent   do not print \`checking ...' messages
1252       --cache-file=FILE   cache test results in FILE [disabled]
1253   -C, --config-cache      alias for \`--cache-file=config.cache'
1254   -n, --no-create         do not create output files
1255       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1256
1257 Installation directories:
1258   --prefix=PREFIX         install architecture-independent files in PREFIX
1259                           [$ac_default_prefix]
1260   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1261                           [PREFIX]
1262
1263 By default, \`make install' will install all the files in
1264 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1265 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1266 for instance \`--prefix=\$HOME'.
1267
1268 For better control, use the options below.

1270 Fine tuning of the installation directories:
1271   --bindir=DIR            user executables [EPREFIX/bin]
1272   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1308 Some influential environment variables:
1309   CC          C compiler command
1310   CFLAGS      C compiler flags
1311   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1312               nonstandard directory <lib dir>
1313   LIBS        libraries to pass to the linker, e.g. -l<library>
1314   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1315               you have headers in a nonstandard directory <include dir>
1316   CPP         C preprocessor
1317
1318 Use these variables to override the choices made by `configure' or to help
1319 it to find libraries and programs with nonstandard names/locations.
