+SUMMARY="Python implementation of the WHATWG Encoding standard"
+DESCRIPTION="In order to be compatible with legacy web content when \
+interpreting something like Content-Type: text/html; charset=latin1, tools \
+need to use a particular set of aliases for encoding labels as well as some \
+overriding rules. For example, US-ASCII and iso-8859-1 on the web are actually \
+aliases for windows-1252, and an UTF-8 or UTF-16 BOM takes precedence over \
+any other encoding declaration. The Encoding standard defines all such details \
+so that implementations do not have to reverse-engineer each other."
