| Subject: [PATCH] Add an option to disable bzip2 support |
| |
| The explicit switch is still on by default, but this way it's possible |
| to explicitly disable bzip2 support even if bzip2 is available on the |
| system. |
| |
| This is useful if bzip2 is not needed, but would automatically lead to |
| an unwanted dependency. |
