autom4te — Generate files and scripts thanks to M4


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.

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


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


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

FORMAT defaults to `$f:$l:$n:$%', and can use the following escapes

literal $
file where macro was called
line where macro was called
nesting depth of macro call
name of the macro
argument NUM, unquoted and with newlines
all arguments, with newlines, quoted, and separated by SEP
all arguments, with newlines, unquoted, and separated by SEP
