/*
Push www strings to Transifex, using scratch-l10n's tx-push-src.js script

1. for every file like src/views/.../l10n.json, call tx-push-src.js
2. also call tx-push-src.js on the general file, src/l10n.json

The format of tx-push-src.js's arguments is:
$ tx-push-src.js tx-project tx-resource english-json-file
So, for example, src/views/parents/l10n.json will use:
$ tx-push-src.js scratch-website parents-l10njson src/views/parents/l10n.json
