// Abstract base class defining interface to common GRID services. //
17
// //
18
// To open a connection to a GRID use the static method Connect(). //
19
// The argument of Connect() is of the form: //
20
// <grid>[://<host>][:<port>], e.g. alien://alice.cern.ch //
21
// Depending on the <grid> specified an appropriate plugin library //
22
// will be loaded which will provide the real interface. //
23
// //
24
// Related classes are TGridResult. //
