* src/Makefile.am (EXTRA_PROGRAMS): Add timeout.
* src/.gitignore: Add timeout binary to list to ignore.
* doc/coreutils.texi (timeout invocation): Add timeout info.
(Signal specifications): New section, also referenced by kill.
* man/Makefile.am (timeout.1): Add dependency.
* man/timeout.x: New file.
* po/POTFILES.in: Add timeout.c and operand2sig.c to list to translate.
* tests/Makefile.am (TESTS): Add the two new tests.
