DESCRIPTION

       is given, else into `configure'.

   Operation modes:
       -h, --help
              print this help, then exit

       -V, --version
              print version number, then exit

       -v, --verbose
              verbosely report processing

       -d, --debug
              don't remove temporary files

       -o, --output=FILE
              save output in FILE (stdout is the default)

       -W, --warnings=CATEGORY
              report the warnings falling in CATEGORY [syntax]

OPTIONS

       `all'  all the warnings

       `no-CATEGORY'
              turn off the warnings on CATEGORY

       `none' turn off all the warnings

       `error'
              warnings are error

       The environment variable `WARNINGS' is honored.

   Library directories:
       -A, --autoconf-dir=ACDIR
              Autoconf's macro files location (rarely needed)

       -l, --localdir=DIR
              location of the `aclocal.m4' file

   Tracing:
       -t, --trace=MACRO
              report the list of calls to MACRO

       -i, --initialization
              also trace Autoconf's initialization process

       In tracing mode, no configuration script is created.
