Generate libwebp Container Spec Docs from Text Source
=====================================================

HTML generation requires kramdown [1], easily installed as a
rubygem [2].  Rubygems installation should satisfy dependencies
automatically.

[1]: http://kramdown.rubyforge.org/
[2]: http://rubygems.org/

HTML generation can then be done from the project root:

$ kramdown doc/webp-container-spec.txt --template doc/template.html > \
  doc/output/webp-container-spec.html

kramdown can optionally syntax highlight code blocks, using CodeRay [3],
a dependency of kramdown that rubygems will install automatically.  The
following will apply inline CSS styling, and then use perl to strip
line numbers and unwanted leading whitespace.

$ kramdown doc/webp-lossless-bitstream-spec.txt --template \
  doc/template.html --coderay-css style | \
  perl -p -e 's|<span class="no">.*?</span>\s||gm' > \
  doc/output/webp-lossless-bitstream-spec.html

Note that code blocks must be immediately followed by a language
identifier for syntax highlighting to succeed.  Example:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
int block_index = (y >> size_bits) * block_xsize +
                  (x >> size_bits);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
{:lang='c'}
