comment {About test/preferences:

The preferences app shows two features of FLTK and FLUID.

The Fl_Preferences class is used as a storage for user
settings between app launches. Fl_Preferences can store
small amounts of arbitrary data in an .ini file format
which can be retrieved again at the next app launch.

The FLUID setup uses GNU gettext for internationalisation
(i18n). FLUID finds the texts that need to be translated
and writes them into .po files that can be processed by
the GNU gettext tools. FLUID produces source code that
will translate all text into the current locale when
generating the UI.


In this small example, 'getttext' is only emulated.} {in_source not_in_header
