gettext_i18n_rails is simple FastGettext Rails integration. Translate via
FastGettext, use any other I18n backend as extension/fallback.

Rails does: I18n.t('syntax.with.lots.of.dots') with nested yml files. We do:
_('Just translate my damn text!') with simple, flat mo/po/yml files or directly
from db. To use I18n, calls add a syntax.with.lots.of.dots translation.
