Pandoc, a universal document converter, is required to generate docs as HTML
from Rust's source code. It's available for most platforms here:
http://johnmacfarlane.net/pandoc/installing.html

Node.js (http://nodejs.org/) is also required for generating HTML from
the Markdown docs (reference manual, tutorials, etc.) distributed with
this git repository.

To generate all the docs, run `make docs` from the root of the repository.
This will convert the distributed Markdown docs to HTML and generate HTML doc
for the 'std' and 'extra' libraries.

To generate HTML documentation from one source file/crate, do something like:

  rustdoc --output-dir html-doc/ --output-format html ../src/libstd/path.rs

(This, of course, requires that you've built/installed the `rustdoc` tool.)

To generate an HTML version of a doc from Markdown, without having Node.js
installed, do something like:

  pandoc --from=markdown --to=html --number-sections -o rust.html rust.md

The syntax for pandoc flavored markdown can be found at:
