%description
Render R Markdown to Markdown (without using 'knitr'), and Markdown to
lightweight HTML or 'LaTeX' documents with the 'commonmark' package
(instead of 'Pandoc'). Some missing Markdown features in 'commonmark' are
also supported, such as raw HTML or 'LaTeX' blocks, 'LaTeX' math,
superscripts, subscripts, footnotes, element attributes, and appendices,
but not all 'Pandoc' Markdown features are (or will be) supported. With
additional JavaScript and CSS, you can also create HTML slides and
articles. This package can be viewed as a trimmed-down version of R
Markdown and 'knitr'. It does not aim at rich Markdown features or a large
variety of output formats (the primary formats are HTML and 'LaTeX'). Book
and website projects of multiple input documents are also supported.
