update_po.py for Gramps translations.
|
|
|
|
Examples:
|
|
python update_po.py -t
|
|
|
|
Tests if 'gettext' and 'python' are well configured.
|
|
|
|
python update_po.py -h
|
|
|
|
Calls help and command line interface.
|
|
|
|
python update_po.py -p
|
|
|
|
Generates a new template/catalog (gramps.pot).
|
|
|
|
python update_po.py -m de.po
|
|
|
|
Merges 'de.po' file with 'gramps.pot'.
|
|
|
|
python update_po.py -k de.po
|
|
|
|
Checks 'de.po' file, tests to compile and generates a textual resume.
