-"""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. b/8654490
-
-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.
