-This package contains the sources to the Android emulator program.
+Read the documentation in qemu-doc.html.
-This program emulates a virtual ARM board that can be used to run Android
-system images on a typical developer machine. To do so, you'll need additionnal
-files provided with the public Android Software Development Kit (SDK).
-
-To download them, go to http://code.google.com/android/
-
-Emulator-specific documentation is available at the following page:
-
- http://code.google.com/android/reference/emulator.html
-
-Please read the INSTALL file to see how you can rebuild the emulator, or
-build a source distribution package tarball.
-
-Read the CHANGES.TXT file to see what important changes were added since
-the last release.
-
-Note: This program is distributed under the terms of the GNU General Public
- License, which exact licensing conditions are available in the COPYING
