MyCV is an easy-to-use web-based framework to create a showcase CV. The main advantage is its extreme simplicity:
you only need to edit an XML file. Since you just need to markup the structure of your CV without thinking in visual appearance artifacts, you'll end up with a robust resulting formatting. Although the 'base' output is XHTML code, more formats can be generated (e.g., vCard or PDF).
Change theme: minimal, narrow, or coolcenter.
Take a look at the source file, the DTD used for validation, and of course the README file.
Documentation will be available soon.
