I decided to give a try at using rst to create my resume : here is the input file.
Now, thanks to this rst to pdf converter project (written in my favourite language), I can easily generate a nice pdf version of my resume. Here is the resulting pdf.
This approach has many advantages compared to my previous way of doing (using open office). I can easily update the document, change the style, and generate my resume not only in pdf, but also in html or almost any formats I want.
 : as some people pointed out, the input file for my CV needs an extra file for the style. This file can be found here.
