Adding Translation Capability

One can add the ability to have Python text messages included for translation. To provide an error message, rather than using the Python sys.stderr, use the provided errormsg() function from in conjunction with gettext.

You must include the following at the beginning of your Python script:

import inkex

Note: In prior versions (0.49), you will have to include the following lines instead:

import inkex
import gettext
_ = gettext.gettext

Where you wish to have an error message, write the following:

inkex.errormsg(_("This will be written to Python stderr"))

Of course, you may also change "_" to something else if you wish.
