Do you want to keep a document with more languages and/or optional sections and maybe being able to turn on/off them whether necessary? The Comment package is the answer to these questions! I show you in WriteLaTeX how to set it with a practical template.
I would never have imagined that I could type a TeX file, view its real-time preview, download the resulting PDF, share it and much more in the Cloud... Yet using WriteLatex it is possible, also without a registration. That's amazing! Finally I can not only edit my templates on the net, but also I manage them from anywhere and on any device.
In these last days I had to find another template for my resume, because people suggest me that Europass CV style is not much appreciate in England. I hope that the following links and examples shall help you to realize a good CV of course using LaTeX.
Today, I will publish the template used for my thesis, it has been updated with the new glossaries package, cleaned and well commented. I think that it is still useful to writing this type of document and others and at the same time it contains some stimulus for reflection for whom is starting to elaborate complex books with table of contents, glossary and bibliography.
