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. 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 (default) override user redefinitions of Automake rules or variables portability portability issues (default in gnu and gnits modes) portability-recursive nested Make variables (default with -Wportability) extra-portability extra portability issues related to obscure tools 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.
