-The goal of this book is to document known and unknown methods of
-doing various tasks using only built-in `bash` features. Using the snippets
-from this bible can help to remove unneeded dependencies from scripts
-and in most cases make them that little bit faster. I came across these
-tips and discovered a few while developing
-[neofetch](https://github.com/dylanaraps/neofetch),
-[pxltrm](https://github.com/dylanaraps/pxltrm) and some other smaller
