language Python written in 100% Pure Java, and seamlessly integrated with
the Java platform. It thus allows you to run Python on any Java platform.

# What follows is used to provide support for I18N in the rest of the
# 4Suite-derived packages in PyXML.
#
# Each sub-package of the top-level "xml" package that contains 4Suite
# code is really a separate text domain, but they're all called
# '4Suite'. For each domain, a translation object is provided using
# message catalogs stored inside the package. The code below defines
# a get_translator() function that returns an appropriate gettext
# function to be used as _() in the sub-package named by the
# parameter. This handles all the compatibility issues related to
# Python versions (whether the gettext module can be found) and
# whether the message catalogs can actually be found.
