23 // TAlienPackage //
24 // //
25 // Class providing package management functionality like the AliEn //
26 // Package Management System. //
27 // Allows to setup software packages on a local desktop like in the //
28 // GRID environment and to execute the contained programs. //
29 // Registered Dependencies are automatically resolved and missing //
30 // packages are automatically installed. //
31 // Currently there is no support for 'source' packages. //
32 // The desired platform has to be specified in the constructor. //
33 // The default constructor takes packages from the global package //
34 // section in AliEn. If you want to install a user package, you have to //
35 // set the AliEn package directory to your local package directory using//
36 // 'package->SetAliEnMainPackageDir("/alice/cern.ch/user/..../packages")//
37 // //
38 // ---------------------------------------------------------------------/////////////////////////
39 // Examples of use: //
40 // root [0] TAlienPackage* package = new TAlienPackage("AliRoot","v4-07-Rev-01","Linux-i686"); //
41 // root [1] package->Exec("aliroot -b -q ") //
42 // //
43 // root [0] TAlienPackage* package = new TAlienPackage("ROOT","v5-16-00","Linux-i686"); //
44 // root [1] package->Exec("root -b -q ") //
