hammer: undelete and questions

[Petr Janda <elekktretterr@xxxxxxxxxxxxxx>]

Hey all,
Im still trying to figure out how to undelete a file (without going to 
snapshots). Undo complains that file doesnt exist or has been renamed, 

1) what else can I do? 

2) How do I access transaction history of a file that I deleted?

Thanks,
PEtr
