17// TAlienFile //
18// //
19// A TAlienFile is like a normal TFile except that it reads and writes //
20// it's data via TXNetFile and gets authorization and the TXNetFile //
21// URL from an alien service. //
22// //
23// Filenames are standard URL format with protocol "alien". //
24// The following are valid TAlienFile URL's: //
25// //
26// alien:///alice/cern.ch/user/p/peters/test.root //
27// /alien/alice/cern.ch/user/p/peters/test.root //
28// //
29// - notice that URLs like /alien/alice... are converted internally //
30// to alien://alice... //
31// //
