The setuptool program (setup) is a front-end menu program for a group of other
tools.  The list of options which it presents is assembled by scanning
/etc/setuptool.d for files.

Each file in the directory should contain one or more lines of text.  Each line
contains from one to four fields which are separated by "|" characters.  In
order, they are:
  - the path to the binary to invoke
    (Mandatory)
  - the untranslated name of the application which should be displayed
    (If unset, defaults to the path of the binary, but don't depend on that.)
  - the gettext textdomain in which a translation of the name of the
    application can be found
    (If unset, defaults to "setup".)
  - the directory in which translations for the textdomain can be found
    (If unset, defaults to "/usr/share/locale".)

If multiple entries with the same untranslated name exist, the one which was
read FIRST takes precedence.  Files are read in name collation order.

A contrived example would create /etc/setuptool.d/00bogus with these contents:
  /bin/ls --color; /bin/sleep 5|Example "ls" invocation.
or
  /bin/ls --color; /bin/sleep 5|Give this help list|libc
to use one of libc's (not meaningful here, but) translateable messages.
