+SUMMARY="Python style guide checker"
+DESCRIPTION="pycodestyle is a tool to check your Python code against some of the style conventions \
+in PEP 8.
+This package used to be called pep8 but was renamed to pycodestyle to reduce confusion.
+Further discussion can be found in the issue where Guido requested this change.
+Features
+* Plugin architecture: Adding new checks is easy.
+* Parseable output: Jump to error location in your editor.
+* Small: Just one Python file, requires only stdlib. You can use just the pycodestyle.py file for \
+this purpose.
+* Comes with a comprehensive test suite."
