   1384 Usage: $0 [OPTION]... [VAR=VALUE]...
   1385 
   1386 To assign environment variables (e.g., CC, CFLAGS...), specify them as
   1387 VAR=VALUE.  See below for descriptions of some of the useful variables.
   1388 
   1389 Defaults for the options are specified in brackets.

   1392   -h, --help              display this help and exit
   1393       --help=short        display options specific to this package
   1394       --help=recursive    display the short help of all the included packages
   1395   -V, --version           display version information and exit
   1396   -q, --quiet, --silent   do not print \`checking ...' messages
