### How to get the condDB tag and more info
Thanks to Vanya, one can easily obtain the most important information about any MC sample. Assuming we want to get information about a process B+ -> mu+ mu- (K*+ -> K+ pi0), which has the *EventType* number `12113100`, we do
```
export PATH=$PATH:/afs/cern.ch/user/i/ibelyaev/public/scripts
lhcb-proxy-init
get_bookkeeping_info 12113100
```
### xml Files
The catalogs stored in `xmlFiles` folder contain information needed to download the corresponding files from the grid. These might be obsolete as the data is not stored there forever. **TODO** add some more information about how to generate them and use them
### Getting lfns
**TODO**
File Code/Gnaga/lfnFiles/get_LFNs.py, try it out and explain
