sent (simple plaintext presentation tool)

sent does not need latex, libreoffice or any other fancy file format, it
uses plaintext files to describe the slides and can also display images.
The presentation is displayed in a simple X11 window.

Patches from upstream after release 1 are included.
If you want to add more patches, place them in the 'patches' directory
and update the series file.

Optional dependency: farbfeld (include images).
