I would like for the po plugin to optionally run from the working directory the transifex-client command equivalent to
tx set --auto-local -r $transifex_project_name.$mungedpagename $mungedpagename'.<lang>.po' --source-lang en --source-file $page.pot --execute
for any new .pot files that are added in that particular ikiwiki run, and then run
tx push -s
each time.
