1322 \`configure' configures TeX Live texk 2016/dev to adapt to many kinds of systems.
1323
1324 Usage: $0 [OPTION]... [VAR=VALUE]...
1325
1326 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1327 VAR=VALUE.  See below for descriptions of some of the useful variables.
1328
1329 Defaults for the options are specified in brackets.
1330
1331 Configuration:
1332   -h, --help              display this help and exit
1333       --help=short        display options specific to this package
1334       --help=recursive    display the short help of all the included packages
1335   -V, --version           display version information and exit
1336   -q, --quiet, --silent   do not print \`checking ...' messages
1337       --cache-file=FILE   cache test results in FILE [disabled]
1338   -C, --config-cache      alias for \`--cache-file=config.cache'
1339   -n, --no-create         do not create output files
1340       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1341
1342 Installation directories:
1343   --prefix=PREFIX         install architecture-independent files in PREFIX
1344                           [$ac_default_prefix]
1345   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1346                           [PREFIX]
1347
1348 By default, \`make install' will install all the files in
1349 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1350 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1351 for instance \`--prefix=\$HOME'.
1352
1353 For better control, use the options below.

1355 Fine tuning of the installation directories:
1356   --bindir=DIR            user executables [EPREFIX/bin]

1507 Some influential environment variables:
1508   CC          C compiler command
1509   CFLAGS      C compiler flags
1510   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1511               nonstandard directory <lib dir>
1512   LIBS        libraries to pass to the linker, e.g. -l<library>
1513   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1514               you have headers in a nonstandard directory <include dir>
1515
1516 Use these variables to override the choices made by `configure' or to help
1517 it to find libraries and programs with nonstandard names/locations.

4707 on the command line, even when the '-f' option is present.  This is contrary

4709 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
4710
