  22 Usage: $0 [OPTION] ... [TEMPLATE-FILE]
  23
  24 Generate a configuration script from a TEMPLATE-FILE if given, or
  25 \`configure.ac' if present, or else \`configure.in'.  Output is sent
  26 to the standard output if TEMPLATE-FILE is given, else into
  27 \`configure'.

  29 Operation modes:
  30   -h, --help                print this help, then exit
  31   -V, --version             print version number, then exit
  32   -v, --verbose             verbosely report processing
  33   -d, --debug               don't remove temporary files
  34   -f, --force               consider all files obsolete
  35   -o, --output=FILE         save output in FILE (stdout is the default)
  36   -W, --warnings=CATEGORY   report the warnings falling in CATEGORY [syntax]
  37
  38 Warning categories include:
  39   \`cross'         cross compilation issues
  40   \`obsolete'      obsolete constructs
  41   \`syntax'        dubious syntactic constructs
  42   \`all'           all the warnings
  43   \`no-CATEGORY'   turn off the warnings on CATEGORY
  44   \`none'          turn off all the warnings
  45   \`error'         warnings are error
  46
  47 The environment variable \`WARNINGS' is honored.
  48
  49 Library directories:
  50   -B, --prepend-include=DIR  prepend directory DIR to search path
  51   -I, --include=DIR          append directory DIR to search path
  52
  53 Tracing:
  54   -t, --trace=MACRO     report the list of calls to MACRO
  55   -i, --initialization  also trace Autoconf's initialization process
  56
  57 In tracing mode, no configuration script is created.
