Oops! Sorry, I’m still translating this post.

In the meantime you can read the original post in Spanish.

In a few words, this post explains a presentation template that I made. The special thing about it is that you can generate several PDFs of different aspect ratios from the same sources.

You can download the presentation template from: https://github.com/mkrevuelta/TheNothingPresentation.

You will also need to download UseLATEX.cmake (which you can get in https://cmake.org/Wiki/CMakeUserUseLATEX and in https://github.com/kmorel/UseLATEX) and copy it in the same folder of the CMakeLists.txt.
