Based on Knuths Vanilla style.

A better mark-up system (e.

A greater variety of document types article, book, etc.

You type an ASCII (text) file with the extension.

You do not worry about formatting.

X To emphasize text, you type: em Emphasize this What you will (probably) get: Emphasize this.

Variables in italics, numbers in Roman, lots of math symbols There In contrast, text is set in text mode.

X violates a common custom of notation: Delimiters should come in left and right pairs.

For all epsilon0 there exists delta so stylemax-height: 312px.

For all epsilon0 there exists delta so that if x-y 0 there exists 0 so that if x - y.

Nesting is allowed with Given a bounded sequence x1, x2, dots, there exists a convergent subsequence xi1, xi2, dots.

Given a bounded sequence x 1, x 2,, there exists convergent subsequence.
