   1338 'configure' configures xrandr 1.5.3 to adapt to many kinds of systems.
   1339 
   1340 Usage: $0 [OPTION]... [VAR=VALUE]...
   1341 
   1342 To assign environment variables (e.g., CC, CFLAGS...), specify them as
   1343 VAR=VALUE.  See below for descriptions of some of the useful variables.
   1344 
   1345 Defaults for the options are specified in brackets.
   1346 
   1347 Configuration:
   1348   -h, --help              display this help and exit
   1349       --help=short        display options specific to this package
   1350       --help=recursive    display the short help of all the included packages
   1351   -V, --version           display version information and exit
   1352   -q, --quiet, --silent   do not print 'checking ...' messages
   1353       --cache-file=FILE   cache test results in FILE [disabled]
   1354   -C, --config-cache      alias for '--cache-file=config.cache'
   1355   -n, --no-create         do not create output files
   1356       --srcdir=DIR        find the sources in DIR [configure dir or '..']
   1357 
   1358 Installation directories:
   1359   --prefix=PREFIX         install architecture-independent files in PREFIX
   1360                           [$ac_default_prefix]
   1361   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
   1362                           [PREFIX]
   1363 
   1364 By default, 'make install' will install all the files in
   1365 '$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
   1366 an installation prefix other than '$ac_default_prefix' using '--prefix',
   1367 for instance '--prefix=\$HOME'.
   1368 
   1369 For better control, use the options below.
