Pootle has many checks, but there are cases which are not covered.
Therefore I wrote a tool which checked three types of translation
errors:
1. Unique style names.
2. Unique spreadsheet function names.
3. Missing trailing '|' in Windows installer translation.
Usage: make cmd cmd=solver/*/bin/pocheck
It checks all languages and prints the report to stdout.
