  25 Usage: $0 [OPTION] ... [TEMPLATE-FILE]
  26
  27 Generate a configuration script from a TEMPLATE-FILE if given, or
  28 \`configure.ac' if present, or else \`configure.in'.  Output is sent
  29 to the standard output if TEMPLATE-FILE is given, else into
  30 \`configure'.
  31
  32 Operation modes:
  33   -h, --help                print this help, then exit
  34   -V, --version             print version number, then exit
  35   -v, --verbose             verbosely report processing
  36       --clean               remove files installed by autoconf
  37   -d, --debug               don't remove temporary files
  38   -f, --force               consider all files obsolete
  39   -o, --output=FILE         save output in FILE (stdout is the default)
  40   -W, --warnings=CATEGORY   report the warnings falling in CATEGORY [syntax]
  41
  42 Warning categories include:
  43   \`cross'         cross compilation issues
  44   \`obsolete'      obsolete constructs
  45   \`syntax'        dubious syntactic constructs
  46   \`all'           all the warnings
  47   \`no-CATEGORY'   turn off the warnings on CATEGORY
  48   \`none'          turn off all the warnings
  49   \`error'         warnings are error
  50
  51 The environment variables \`M4' and \`WARNINGS' are honored.
  52
  53 Library directories:
  54   -B, --prepend-include=DIR  prepend directory DIR to search path
  55   -I, --include=DIR          append directory DIR to search path
  56
  57 Tracing:
  58   -t, --trace=MACRO     report the list of calls to MACRO
  59   -i, --initialization  also trace Autoconf's initialization process
  60
  61 In tracing mode, no configuration script is created.
