3.5. Proofreading

To proofread your translation as part of the software, follow these steps:

Change directory to the package you want to proofread. For example,
```
cd ~/myproject/system-config-printer/
```
Convert the .po file to a .mo file using msgfmt with -o option:
```
msgfmt -o system-config-printer.mo ja.po
```
As a root user, overwrite the existing .mo file in /usr/share/locale/lang/LC_MESSAGES/.
First, back up the existing file:
```
su -
```
```
cp /usr/share/locale/ja/LC_MESSAGES/system-config-printer.mo system-config-printer.mo-backup
```
Now move the file converted for proofreading.
```
mv system-config-printer.mo /usr/share/locale/ja/LC_MESSAGES/
```
Exit root user.
```
exit
```
Proofread the package with the translated strings as part of the application:
```
LANG=ja_JP.UTF-8 system-config-printer
```

The application related to the translated package runs with the translated strings.
