* Unificar els repos (tret de http://stackoverflow.com/questions/277029/combining-multiple-git-repositories)

Here's a solution I gave here:

First do a complete backup of your phd directory: I don't want to be held responsible for your losing years of hard work! ;-)

$ cp -r phd phd-backup
Move the content of phd/code to phd/code/code, and fix the history so that it looks like it has always been there (this uses git's filter-branch command):

$ cd phd/code
