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").
This file is included in worg mainly less for viewing through the web interface, and more for contribution through the worg git repository. If you have code snippets that you think others may find useful please add them to this file and contribute them to worg.
The raw Org-mode text of this file can be downloaded at library-of-babel.org
