 """Convert Android xml resources to API 14 compatible.
 
 There are two reasons that we cannot just use API 17 attributes,
 so we are generating another set of resources by this script.
 
 1. paddingStart attribute can cause a crash on Galaxy Tab 2.
 2. There is a bug that paddingStart does not override paddingLeft on
    JB-MR1. This is fixed on JB-MR2.
 
 Therefore, this resource generation script can be removed when
 we drop the support for JB-MR1.
 
 Please refer to http://crbug.com/235118 for the details.
