Introduction

The Library of Babel is an extensible collection of ready-made and easily-shortcut-callable source-code blocks for handling common tasks. Org-babel comes pre-populated with the source-code blocks located in this file. It is possible to add source-code blocks from any org-mode file to the library by calling (org-babel-lob-ingest "path/to/file.org").
