pocommentclean will remove all translator comments from a directory of PO files.
pocommentclean [--backup] <po>
is a directory of existing PO files that you want to clean
Create a backup file for each PO file converted, .po.bak
Using sed pocommentclean will delete all lines starting with # but which are not standard Gettext PO format lines. So it won’t delete developer comments (#.), obsolete messages (#~), flags (#,) or locations (#:).
pocommentclean cannot clean individual PO files, it only cleans directories
