Creating your own style
With Ortelius you can use the default styles, or you can create your own style. All you need is to add an xslt file and a folder with your css, javascript and graphic files. The folder should be named with the same name as the the xsl file.
You put theese files in the directory with the applikation. This is usualy 'Program Files>Ortelius 2.0>styles'.
If you have created your own style, you are more than welcome to e-mail it to me. Then i'll add it to the following release.
If you want to create minor changes, you can just copy one of the existing styles, rename it and change the things you wants different.
