[docbook-css] Customisation layers

[David Holroyd]

I was going to allow for customisations be adding an extra @import to
driver.css, like this:

  @import "core.css";
  @import "tables.css";
  @import "styles.css";
  @import "mozilla.css";
  @import "opera.css";
  /* Local customisations to docbook-css should be added in local.css */
  @import "local.css";

An example local.css would appear in the distribution files.

Problem is, this means that someone unpacking a new set of
distribution files would overwrite any changes to local.css in addition
to updating the core stylesheets.


I was thinking it would be better to just create a custom .css file for
local changes, and have that @import "driver.css".  This would make it a
bit simpler to implement multiple customisation layers all sharing the
same copy of docbook-css, too.


Seems sensible?
