  24
  25 Generate a configuration script from a TEMPLATE-FILE if given, or
  26 \`configure.ac' if present, or else \`configure.in'.  Output is sent

  28 \`configure'.

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