AUTOM4TE(1)                      User Commands                     AUTOM4TE(1)

NAME
       autom4te - Generate files and scripts thanks to M4

SYNOPSIS
       autom4te [OPTION]... [FILES]

DESCRIPTION
       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, to-
       gether 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.

       `override'
              user redefinitions of Automake rules or variables

   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
