+//<pre>
//_____________________________________________________________
// AliL3Transform
//
// Transformation class for ALICE TPC.
+//
+// Class which contains all detector specific parameters for the TPC,
+// and different useful functions for coordinate transforms.
+//
+// The class is completely static, which means that no object needs
+// to be instantiated. Function calls should then be done like, e.g.:
+//
+// Double_t eta = AliL3Transform::GetEta(xyz);
+//
+// IMPORTANT: If used as is, default detector parameters will be used,
+// and you really have to make sure that these correspond to
+// the AliROOT version you are currently working on!!
+// You should therefore always initialize the parameters by
+//
+// AliL3Transform::Init(path);
+//
+// where path is a char*, giving the path to where file containing
+// the detector parameter is located. This file should be called
+// "l3transform.config", and can be created with the function MakeInitFile.
+//
+// You can also force reading the parameters from a AliTPCParam object
+// by setting the flag;
+//
+// AliL3Transform::Init(path,kTRUE);
+//
+// where path is a char*
+// either providing the rootfile containing the geometry or
+// the path to the rootfile which should then be called alirunfile.root.
+// Note that for both cases you have to
+// compile with USEPACKAGE=ALIROOT set (see level3code/Makefile.conf).
