That's my (edufcarvalho) dotfiles, I created them to be simple and functional for my personal usage. That dotfiles are not agnostic or flexible in any way, everything is build to MY and probably only my usage.
That dotfiles are tweaked with some uncommon things, but I found these things usefull, then, here they are.
If you're searching for a well developed, well maintained and flexible dotfiles, you came to the wrong place. I recomend the holman's dotfiles, check it out in the link.
