Examples

// Display some additional information
atomsSetConfig("Verbose","True");

// Load the test repository
exec("SCI/modules/atoms/tests/unit_tests/atomsTestUtils.sce", -1);
repository = atomsCreateTestRepository("scene10");

// Install the needed module for the purpose of the example
atomsInstall("toolbox_5V6","user");

// simplest way
atomsIsInstalled("toolbox_5V6");

// Check several modules ...
atomsIsInstalled(["toolbox_5V6" "toolbox_4V6"])

// ... with a specific version
atomsIsInstalled(["toolbox_5V6" "1.0" ; "toolbox_4V6" "1.0" ; "toolbox_V65" "1.1"])

// ... installed in a specific section
atomsIsInstalled(["toolbox_5V6" "1.0" ; "toolbox_4V6" "1.0" ; "toolbox_5V6" "1.1"],"user")
atomsIsInstalled(["toolbox_5V6" "1.0" ; "toolbox_4V6" "1.0" ; "toolbox_5V6" "1.1"],"allusers")

// Cleaning
atomsRemove(["toolbox_1V6"; ..
             "toolbox_2V6"; ..
             "toolbox_4V6"; ..
