Ouro Loot HTML
This is a Raw HTML plugin for Ouro Loot. Installing it will add an output tab for HTML markup.
There are (mostly placeholder, though functional) editboxes controlling what HTML tags are used for marking up the encounter output, which otherwise is the same as the default forum markup. It's currently not suitable for full-on CSS or anything like that, but suggestions are welcome.
This also serves as an example for plugin formats. It may expand to add a generic XML output tab as well, depending on who/what would be using it (possibly a replacement for the ML/EQDKP experimental tab).
