 1256 \`configure' configures zsync 0.6.2 to adapt to many kinds of systems.
 1257 
 1258 Usage: $0 [OPTION]... [VAR=VALUE]...
 1259 
 1260 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1261 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1262 
 1263 Defaults for the options are specified in brackets.
 1264 
 1265 Configuration:
 1266   -h, --help              display this help and exit
 1267       --help=short        display options specific to this package
 1268       --help=recursive    display the short help of all the included packages
 1269   -V, --version           display version information and exit
 1270   -q, --quiet, --silent   do not print \`checking...' messages
 1271       --cache-file=FILE   cache test results in FILE [disabled]
 1272   -C, --config-cache      alias for \`--cache-file=config.cache'
 1273   -n, --no-create         do not create output files
 1274       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1275 
 1276 Installation directories:
 1277   --prefix=PREFIX         install architecture-independent files in PREFIX
 1278                           [$ac_default_prefix]
 1279   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1280                           [PREFIX]
 1281 
 1282 By default, \`make install' will install all the files in
 1283 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1284 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1285 for instance \`--prefix=\$HOME'.
 1286 
 1287 For better control, use the options below.

 1336   --disable-dependency-tracking  speeds up one-time build
 1337   --enable-dependency-tracking   do not reject slow dependency extractors
 1338   --enable-profile        Turns on profiling
 1339   --disable-largefile     omit support for large files

 1347 Some influential environment variables:
 1348   CC          C compiler command
 1349   CFLAGS      C compiler flags
 1350   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1351               nonstandard directory <lib dir>
 1352   LIBS        libraries to pass to the linker, e.g. -l<library>
 1353   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1354               you have headers in a nonstandard directory <include dir>
 1355   CPP         C preprocessor
 1356 
 1357 Use these variables to override the choices made by `configure' or to help
 1358 it to find libraries and programs with nonstandard names/locations.
