Original commit message from CVS:
element categories
- all bitrates should be bits per second, since they're specified
as integers
+
+- categorization of plugins:
+ - categories were intended from the start as a list of keywords, instead
+ of an implicit tree.
+ - this makes a lot more sense and probably fixes our constant discussion
+ about categorizing
+ - make this explicit by having a list of keywords instead of a fixed string
+ with slashes
+ - fix the editor/el browser to display this nicely
