the patch below updates the readme.txt for l10n_client to reflect changes in drupal 7
2 questions still:
1. in d6 there was the option to see all the website's interface strings by selecting Translate
Strings from the menu (http://www.example.com/locale).
Does that still work? The list of string seems to be empty
2. the D6 version included the option to reimport strings via Configuration > Regional and language > Translate interface >
Import > Reimport packages. Does that still exist?
