Restless is yet-another lightweight markup
processor; it generates HTML from plain text with
non-intrusive markup of headings, bullet lists,
and so on. But unlike other such tools, restless
aims to do less: it does not use cryptic
punctuation to control advanced formatting, and
instead uses heuristics to classify, for example,
code samples versus text. It can be used from the
command line or on-demand as an Apache filter.
