  27 Usage: $0 [OPTION]... [TEMPLATE-FILE]
  28
  29 Generate a configuration script from a TEMPLATE-FILE if given, or
  30 \`configure.ac' if present, or else \`configure.in'.  Output is sent
  31 to the standard output if TEMPLATE-FILE is given, else into
  32 \`configure'.
  33
  34 Operation modes:
  35   -h, --help                print this help, then exit
  36   -V, --version             print version number, then exit
  37   -v, --verbose             verbosely report processing
  38   -d, --debug               don't remove temporary files
  39   -f, --force               consider all files obsolete
  40   -o, --output=FILE         save output in FILE (stdout is the default)
  41   -W, --warnings=CATEGORY   report the warnings falling in CATEGORY [syntax]
  42
  43 Warning categories include:
  44   \`cross'         cross compilation issues
  45   \`obsolete'      obsolete constructs
  46   \`syntax'        dubious syntactic constructs
  47   \`all'           all the warnings
  48   \`no-CATEGORY'   turn off the warnings on CATEGORY
  49   \`none'          turn off all the warnings
  50   \`error'         warnings are error
  51
  52 The environment variables \`M4' and \`WARNINGS' are honored.
  53
  54 Library directories:
  55   -B, --prepend-include=DIR  prepend directory DIR to search path
  56   -I, --include=DIR          append directory DIR to search path
  57
  58 Tracing:
  59   -t, --trace=MACRO[:FORMAT]  report the list of calls to MACRO
  60   -i, --initialization        also trace Autoconf's initialization process
  61
  62 In tracing mode, no configuration script is created.  FORMAT defaults
  63 to \`\$f:\$l:\$n:\$%'; see \`autom4te --help' for information about FORMAT.
