python3-markdown-callouts 0.4.0-1 (i386 binary) in ubuntu oracular

 This package extends the functionality of Python Markdown by turning a
 paragraph of text into a block that's specially highlighted and set apart from
 the rest of the text.
 .
 This extension produces the same results as the admonition extension, but with
 a syntax that is much less intrusive and has a very reasonable fallback look
 for "vanilla" renderers.
