8 Purpose: automatic initialization of Ganga environment setup and software distribution tools.

10 Each PACKAGE module should provide:
11 - setup object : an instance of Ganga.Utility.Setup.PackageSetup class
12 - standardSetup() function
13
14 The setup object is used to describe the external dependencies of the package.
15 The standardSetup() function is used to perform automatic initialization of the environment of the package.

75 Ganga provides precompiled external packages on a limited set of _default platforms_ as explained in:
76 https://twiki.cern.ch/twiki/bin/view/ArdaGrid/GangaSupportedPlatforms
77 This function is set only to detect the well-known platform strings as defined by the LCG SPI project and is not meant to be a
78 generic platform detection utility. If the platform cannot be guessed a default one is returned. This may or may not work on
79 other systems. In this case you should resolve the external binary dependencies yourself.
