  26 Usage: $0 [OPTION]... [TEMPLATE-FILE]
  27
  28 Generate a configuration script from a TEMPLATE-FILE if given, or
  29 'configure.ac' if present, or else 'configure.in'.  Output is sent
  30 to the standard output if TEMPLATE-FILE is given, else into
  31 'configure'.
  32
  33 Operation modes:
  34   -h, --help                print this help, then exit
  35   -V, --version             print version number, then exit
  36   -v, --verbose             verbosely report processing
  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[:FORMAT]  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.  FORMAT defaults
  62 to '\$f:\$l:\$n:\$%'; see 'autom4te --help' for information about FORMAT.
