-Note that the grid mixin requires you to pass in columns of the parent
+While this example uses 12 and 16 as column numbers, you can use any
+arbitrary number of columns and the code will do the calculation for you.
+However, if it doesn't divide up cleanly it just won't.
+The grid mixin requires you to pass in columns of the parent
container as the second argument. Someone let me know if there's a
better way to obtain this information.
until all browsers get better support for that in css, this is
+### Overriding width and padding
+The grid system defaults to 960px width with 10px padding around all
+grid elements. You can override these values by setting the appropriate
+variables in your global namespace
+ @ninesixty_width = 960px;
+ @ninesixty_padding = 10px;
+Please note that 960 is a pretty magic number and your grid widths
+might not cleanly divide by whatever your column number is.
