133	133	The other big part next to date formatting are translations. For that,
134	134	Flask uses :mod:`gettext` together with Babel. The idea of gettext is
135	135	that you can mark certain strings as translatable and a tool will pick all
136		those app, collect them in a separate file for you to translate. At
	136	those up, collect them in a separate file for you to translate. At
137	137	runtime the original strings (which should be English) will be replaced by
138	138	the language you selected.
