  91 Usage: $0 [OPTION] ... [TEMPLATE-FILE]
  92
  93 Generate a configuration script from a TEMPLATE-FILE if given, or
  94 \`configure.ac' if present, or else \`configure.in'.  Output is sent
  95 to the standard output if TEMPLATE-FILE is given, else into
  96 \`configure'.
  97
  98 Operation modes:
  99   -h, --help                print this help, then exit
 100   -V, --version             print version number, then exit
 101   -v, --verbose             verbosely report processing
 102   -d, --debug               don't remove temporary files
 103   -f, --force               consider all files obsolete
 104   -o, --output=FILE         save output in FILE (stdout is the default)
 105   -W, --warnings=CATEGORY   report the warnings falling in CATEGORY [syntax]
 106
 107 Warning categories include:
 108   \`cross'         cross compilation issues
 109   \`obsolete'      obsolete constructs
 110   \`syntax'        dubious syntactic constructs
 111   \`all'           all the warnings
 112   \`no-CATEGORY'   turn off the warnings on CATEGORY
 113   \`none'          turn off all the warnings
 114   \`error'         warnings are error
 115
 116 The environment variable \`WARNINGS' is honored.
 117
 118 Library directories:
 119   -B, --prepend-include=DIR  prepend directory DIR to search path
 120   -I, --include=DIR          append directory DIR to search path
 121
 122 Tracing:
 123   -t, --trace=MACRO     report the list of calls to MACRO
 124   -i, --initialization  also trace Autoconf's initialization process
 125
 126 In tracing mode, no configuration script is created.
