"""CDS Invenio international messages functions, to be used by all
I18N interfaces. Typical usage in the caller code is:
from messages import gettext_set_language
[...]
def square(x, ln=cdslang):
_ = gettext_set_language(ln)
print _("Hello there!")
print _("The square of %s is %s.") % (x, x*x)
In the caller code, all output strings should be made translatable via
the _() convention.
