	sent is a simple plaintext presentation tool.

	sent does not need latex, libreoffice or any other fancy file format, it uses
	-plaintext files and png images. Every paragraph represents a slide in the
	-presentation.
	+plaintext files to describe the slides and can include images via farbfeld.
	+Every paragraph represents a slide in the presentation.

	The presentation is displayed in a simple X11 window. The content of each slide
	is automatically scaled to fit the window and centered so you also don't have …
	worry about alignment. Instead you can really concentrate on the content.


	+Dependencies
	+
	+You need Xlib to build sent and the farbfeld[0] tools installed to use images …
	+your presentations.
