|---|
| 3 | # if msgmerge output is empty, prints the content of the file named the first |
|---|
| 4 | # argument. otherwise it prints the output of msgmerge. The wrapper should be |
|---|
| 5 | # "compatible" with the real msgmerge if msgmerge output is non-empty, or if the |

| 6 | # first argument is the defpo file (instead of an option, or --) |

| 10 | # The purpose is to provide a workaround for ruby-gettext, which treats empty output |
|---|
| 11 | # from msgmerge as error in the po file, where it should mean that no modification |
|---|
| 12 | # is needed to the defpo. For updates on the issue follow |
