%description
Write beautiful yet customizable letters in R Markdown and directly obtain
the finished PDF. Smooth generation of PDFs is realized by 'rmarkdown',
the 'pandoc-letter' template and the 'KOMA-Script' letter class.
'KOMA-Script' provides enhanced replacements for the standard 'LaTeX'
classes with emphasis on typography and versatility. 'KOMA-Script' is
particularly useful for international writers as it handles various paper
formats well, provides layouts for many common window envelope types (e.g.
German, US, French, Japanese) and lets you define your own layouts. The
package comes with a default letter layout based on 'DIN 5008B'.
