+Cython is a language that makes writing C extensions for Python as easy
+as Python itself. Cython is based on Pyrex, but supports more cutting
+edge functionality and optimizations.
+
+The Cython language is very close to the Python language, but Cython
+additionally supports calling C functions and declaring C types on
+variables and class attributes. This allows the compiler to generate
+very efficient C code from Cython code.
+
+This makes Cython the ideal language for wrapping external C libraries,
+and for fast C modules that speed up the execution of Python code.

+hatch-fancy-pypi-readme is a Hatch metadata plugin for everyone who
+cares about the first impression of their project’s PyPI landing page.
+It allows you to define your PyPI project description in terms of
+concatenated fragments that are based on static strings, files, and most
+importantly: parts of files defined using cut-off points or regular
+expressions.
+
+Once you’ve assembled your readme, you can additionally run regular
+expression-based substitutions over it. For instance to make relative
+links absolute or to linkify users and issue numbers in your changelog.
