+Source: qcpufreq
+Section: user/system
+Priority: extra
+Maintainer: Daniel Klaffenbach <danielklaffenbach@gmail.com>
+Build-Depends: debhelper (>= 5), libqt4-dev (>= 4.6.1 )
+Standards-Version: 3.7.3
+
+Package: qcpufreq
+Architecture: any
+Depends: ${shlibs:Depends}, ${misc:Depends}
+Description: A GUI for the kernel's cpufreq interface
+ This application allows you to adjust the maximum CPU
+ frequency that your device is able to use in order to save
+ battery power.
+ It should work with official and patched kernels.
+ Note: changes are NON-permanent. After a reboot your device
+ will use the factory frequency settings and you'll have to
+ launch QCPUFreq again!
