+Attribute Statistics
+---------------------
+
+This program gathers statistics about attribute usage in layout
+files. This is how the "topAttrs" attributes listed in ADT's
+extra-view-metadata.xml file (which drives the common attributes
+listed in the top of the context menu) is determined by running this
+script on a body of sample Android code, such as the AOSP repository.
+
+This program takes one or more directory paths, and then it searches
+all of them recursively for layout files that are not in folders
+containing the string "test", and computes and prints frequency
+statistics.
