[Box Backup] deleting file in the store

[Alexandre Mallais]

On this page http://boxbackup.org/trac/wiki/011

There is a quote that says: "If you have problems with large files (over 
2GB compressed) not being backed up, restored or compared, you will need 
to delete them from the store server to fix them properly. You can do 
this before or after upgrading, but if they are uploaded again by the 
0.10 client then the problem will not be solved."

My current question is not about 2GB files. I just want to know how can 
you delete files in the store server ? There is not command for it with 
bbackupquery. :(
