/* An Android Virtual Device (AVD for short) corresponds to a
* directory containing all kernel/disk images for a given virtual
* device, as well as information about its hardware capabilities,
* SDK version number, skin, etc...
* Each AVD has a human-readable name and is backed by a root
* configuration file and a content directory. For example, an
* AVD named 'foo' will correspond to the following:
* - a root configuration file named ~/.android/avd/foo.ini
* describing where the AVD's content can be found
* - a content directory like ~/.android/avd/foo/ containing all
* disk image and configuration files for the virtual device.
* the 'foo.ini' file should contain at least one line of the form:
* rootPath=<content-path>
* it may also contain other lines that cache stuff found in the
* content directory, like hardware properties or SDK version number.
* it is possible to move the content directory by updating the foo.ini
* file to point to the new location. This can be interesting when your
* $HOME directory is located on a network share or in a roaming profile
* (Windows), given that the content directory of a single virtual device
* can easily use more than 100MB of data.
