Gettext
=======
If `AM_GNU_GETTEXT' is seen in `configure.in', then Automake turns
on support for GNU gettext, a message catalog system for
internationalization (Note:GNU Gettext.).
The `gettext' support in Automake requires the addition of two
subdirectories to the package, `intl' and `po'. Automake insures that
these directories exist and are mentioned in `SUBDIRS'.
Furthermore, Automake checks that the definition of `ALL_LINGUAS' in
`configure.in' corresponds to all the valid `.po' files, and nothing
more.
