@adriansev : I pushed today few commits that implement the functionality.

In `xrdcp` there is a new option `--rm-bad-cksum` that will make the client remove the target file if checksum verification fails (please not that this option enables POSC semantics).

You can also use the functionality from Python, e.g.:

```
from XRootD import client
process = client.CopyProcess()
process.add_job( source='/path/to/metalink.meta4',
                              target='/path/to',
                              force=True,
                              checksummode='end2end',
                              **checksumtype='auto'**,
                              rmBadCksum=True )
process.prepare()
process.run()
```
Please note the `checksum` type is set to `**auto**`, this is also a new functionality (that you asked for) that makes the client infer automatically the checksum type based on source/destination configuration, source file type (metalink, ZIP), and available checksum plug-ins.

Could you please give it a try?
