Very often, developers mess up the executable permissions and shebangs of Python files. For example, sometimes the executable permission was accidentally granted, sometimes it is forgotten.

This is a Flake8 plugin that ensures the executable permissions and shebangs of Python files are correctly set. Specifically, it checks the following errors:

• EXE001: Shebang is present but the file is not executable.
• EXE002: The file is executable but no shebang is present.
• EXE003: Shebang is present but does not contain "python".
• EXE004: There is whitespace before shebang.
• EXE005: There are blank or comment lines before shebang.
