This is my castle
There are others just like it
But this one is mine
In other words, these are my beloved dotfiles, my darlings, my eternally edited and tirelessly tweaked configurations and customizations. They are dear to my heart, my preciousness -- and I hate working on a machine without them.
Fortunately, there's Homesick, a tool for managing, porting, and sharing dotfiles. Collections of dotfiles in Homesick are called Castles; this one is mine. Hence the haiku.
...and now you know. Carry on.
