| /* technical note on how all of this is supposed to work: |
| * |
| * Each AVD corresponds to a "content directory" that is used to |
| * store persistent disk images and configuration files. Most remarkable |
| * are: |
| * |
| * - a "config.ini" file used to hold configuration information for the |
| * AVD |
| * |
| * - mandatory user data image ("userdata-qemu.img") and cache image |
| * ("cache.img") |
| * |
| * - optional mutable system image ("system-qemu.img"), kernel image |
| * ("kernel-qemu") and read-only ramdisk ("ramdisk.img") |
| * |
| * When starting up an AVD, the emulator looks for relevant disk images |
| * in the content directory. If it doesn't find a given image there, it |
| * will try to search in the list of system directories listed in the |
| * 'config.ini' file through one of the following (key,value) pairs: |
| * |
| * images.sysdir.1 = <first search path> |
| * images.sysdir.2 = <second search path> |
| * |
| * The search paths can be absolute, or relative to the root SDK installation |
| * path (which is determined from the emulator program's location, or from the |
| * ANDROID_SDK_ROOT environment variable). |
| * |
| * Individual image disk search patch can be over-riden on the command-line |
| * with one of the usual options. |

| ***** if the latter doesn't exist. |
| ***** |
| ***** - the kernel and default skin directory are taken from |
| ***** prebuilt |
| ***** |
| ***** - there is no root .ini file, or any config.ini in |
