# '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.
