A Python script to generate a single PDF document with all the `tldr` pages. It works by generating
|
|
|
|
|
intermediate HTML files from existing md files using Python-markdown, applying desired formatting
|
|
|
|
|
through CSS, and finally rendering them as PDF. There is no LaTeX dependency for generating the PDF.
