+# In order to resolve Bug 368716 (https://bugs.launchpad.net/scour/+bug/368716)
+# scour needed a bare-minimum CSS parser in order to determine if some elements
+# were still referenced by CSS properties.
+
+# I looked at css-py (a CSS parser built in Python), but that library 
+# is about 35k of Python and requires ply to be installed.  I just need 
+# something very basic to suit scour's needs.
+
+# yocto-css takes a string of CSS and tries to spit out a list of rules
+# A rule is an associative array (dictionary) with the following keys:
+# - selector: contains the string of the selector (see CSS grammar)
+# - properties: contains an associative array of CSS properties for this rule
+
+# TODO: need to build up some unit tests for yocto_css
