I think the CDATA for the language packs should be in the cTransifex project config or at least in the main config, not in the language strings.
And maybe a more neutral line as not all projects are from OpenTranslators


administrator\language\en-GB\en-GB.com_ctransifex.ini
[code type=ini]
COM_CTRANSIFEX_INSTALL_XML_DESCRIPTION="This package was auto generated with CTransifex(https://compojoom.com). We've grabbed the latest language files for our extension from transifex.com."
COM_CTRANSIFEX_INSTALL_XML_THANKS_OPENTRANSLATORS="Special thanks to OpenTranslators (http://opentranslators.org) for helping us with this translation!"
[/code]

This makes all language packs to display the same translation for the CData! Or do I need to install more language packs?
