Class Description

                                                                      
 TGrid                                                                
                                                                      
 Abstract base class defining interface to common GRID services.      
                                                                      
 To open a connection to a GRID use the static method Connect().      
 The argument of Connect() is of the form:                            
    <grid>[://<host>][:<port>], e.g.                                  
 alien, alien://alice.cern.ch, globus://glsvr1.cern.ch, ...           
 Depending on the <grid> specified an appropriate plugin library      
 will be loaded which will provide the real interface.                
                                                                      
 Related classes are TGridResult.

TGrid* Connect(const char *grid, const char *uid, const char *pw, const char *options)

 The grid should be of the form:  <grid>://<host>[:<port>],
 e.g.:  alien://alice.cern.ch, globus://glsrv1.cern.ch, ...
 The uid is the username and pw the password that should be used for
 the connection. Depending on the <grid> the shared library (plugin)
 for the selected system will be loaded. When the connection could not
 be opened 0 is returned. For AliEn the supported options are:
 -domain=<domain name>
 -debug=<debug level from 1 to 10>
 Example: "-domain=cern.ch -debug=5"

void pwd() const

 Print current working directory.

void cd(const char *dir) const

 Change working directory.

void ls(const char *dir, const char *options) const

 List content of current directory.
 Supported options:
  "l": long listing format
  "a": list all entries
  "d": list only directories
