// 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:
+//
+// 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 macro exa/Make_Init.C.
