Re: [docbook-apps] Dealing with relative CSS files in chunked output

["Bob Stayton" <bobs@sagehill.net>]

Hi,
I discovered this same problem when I started working on generating a CSS 
file and creating the links to it.  I was also surprised it had not come up 
before.  I'm planning to fix it in the next release.
