+Summary:Local OpenCellID based location provider backend for UnifiedNlp
+Description:
+[https://github.com/microg/android_packages_apps_UnifiedNlp UnifiedNlp] backend 
+that implements a cell-tower based lookup for your current location. It ships a 
+binary cell database extracted from [http://opencellid.org OpenCellID]
+This "NetworkLocationProvider" works without network connectivity and will 
+never post your data anywhere. You are thus encouraged to help OpenCellID to 
+gather more cells in order to improve this project.
+[[de.enaikoon.android.keypadmapper3]] can be used to gather cell information 
+for OpenCellID.
