Usage: /usr/bin/autom4te [OPTION]... [FILES]

Run GNU M4 on the FILES, avoiding useless runs.  Output the traces if tracing,
the frozen file if freezing, otherwise the expansion of the FILES.

If some of the FILES are named `FILE.m4f' they are considered to be M4
frozen files of all the previous files (which are therefore not loaded).
If `FILE.m4f' is not found, then `FILE.m4' will be used, together with
all the previous files.

Some files may be optional, i.e., will only be processed if found in the
include path, but then must end in `.m4?';  the question mark is not part of
the actual file name.

Operation modes:
  -h, --help               print this help, then exit
  -V, --version            print version number, then exit
  -v, --verbose            verbosely report processing
  -d, --debug              don't remove temporary files
  -o, --output=FILE        save output in FILE (defaults to `-', stdout)
  -f, --force              don't rely on cached values
  -W, --warnings=CATEGORY  report the warnings falling in CATEGORY
  -l, --language=LANG      specify the set of M4 macros to use
  -C, --cache=DIRECTORY    preserve results for future runs in DIRECTORY
      --no-cache           disable the cache
  -m, --mode=OCTAL         change the non trace output file mode (0666)
  -M, --melt               don't use M4 frozen files

Languages include:
  `Autoconf'   create Autoconf configure scripts
  `Autotest'   create Autotest test suites
  `M4sh'       create M4sh shell scripts
  `M4sugar'    create M4sugar output

Warning categories include:
  `cross'         cross compilation issues
  `gnu'           GNU coding standards (default in gnu and gnits modes)
  `obsolete'      obsolete features or constructions
  `override'      user redefinitions of Automake rules or variables
  `portability'   portability issues (default in gnu and gnits modes)
  `syntax'        dubious syntactic constructs (default)
  `unsupported'   unsupported or incomplete features (default)
  `all'           all the warnings
  `no-CATEGORY'   turn off warnings in CATEGORY
  `none'          turn off all the warnings
  `error'         treat warnings as errors

The environment variables `M4' and `WARNINGS' are honored.

Library directories:
  -B, --prepend-include=DIR  prepend directory DIR to search path
  -I, --include=DIR          append directory DIR to search path

Tracing:
  -t, --trace=MACRO[:FORMAT]  report the MACRO invocations
  -p, --preselect=MACRO       prepare to trace MACRO in a future run

Freezing:
  -F, --freeze   produce an M4 frozen state file for FILES

FORMAT defaults to `$f:$l:$n:$%', and can use the following escapes:
  $$     literal $
  $f     file where macro was called
  $l     line where macro was called
  $d     nesting depth of macro call
  $n     name of the macro
  $NUM   argument NUM, unquoted and with newlines
  $SEP@  all arguments, with newlines, quoted, and separated by SEP
  $SEP*  all arguments, with newlines, unquoted, and separated by SEP
  $SEP%  all arguments, without newlines, unquoted, and separated by SEP
SEP can be empty for the default (comma for @ and *, colon for %),
a single character for that character, or {STRING} to use a string.
