| 156 | --type=TYPE Specify the file type of FILENAME. Currently supports: |

| 158 | "gettext/rfc822deb", "gettext/schemas", |
|---|
| 159 | "gettext/scheme", "gettext/xml" |
|---|
| 160 | -l, --local Writes output into current working directory |
|---|
| 161 | (conflicts with --update) |
|---|
| 162 | --update Writes output into the same directory the source file |
