Usage:

./lang-mangle.rb -u -r -s Enterprise -t Tenant -l lang_en_US-labels.json

That would replace all occurrences of the word Enterprise with Tenant in language file lang_en_US-labels.json.

If you remove the -u parameter it will ask for confirmation in every match (and the file is only written at the end!).
