Description: debut: Utilities to parse Debian package, copyright and control files
        =====================================================================
        
        The Python package `debut` is a collection of utilities to parse various Debian
        package manifests, machine readable copyright and control files collectively
        known as the Debian 822 format (based on the RFC822 email format).
        
        Why the name `debut`? That's a portmanteau of DEBian and UTilities!
        
        
        Origin
        ------
        
        This library is based on a heavily modified and remixed combination of original
        code with code from other origins:
        
        * python-deb-pkg-tools from @xolox for its handling of Debian packages and the
          parsing of dependencies and other package-to-package relationship fields.
          See https://github.com/xolox/python-deb-pkg-tools
        
        * dlt (Debian license tools) from @agustinhenze for its check of the
          coverage of a license file Files sections and a lot of inspiration.
          See https://github.com/agustinhenze/dlt/
        
        * PGPy from @SecurityInnovation and @Commod0re for its ability to remove a PGP
          signature from an email. dsc (Debian Source Control) files are typically
          PGP-signed.
          See https://github.com/SecurityInnovation/PGPy
        
        * python-dpkg by @TheClimateCorporation and @memory for its ability to process
          the syntax of Debian versions and to compare them according to the spec.
          See https://github.com/TheClimateCorporation/python-dpkg
        
        
        Why?
        ----
        
        Why create this seemingly redundant library? The official python-debian tools
        and several other utilities already provide similar capabilities!
        
        On the surface this is correct, but there are several reasons for a new utility:
        
        * Existing tools parse control files strictly. This library tries
          to be more flexible. For instance it can recognize and fix some almost
          correct copyright files that are not fully "machine readable" but close
          enough to the spec to be worthy of recovery.
        
        * Several of these tools have to deal with legacy compatibility. We
          do not have such a need. For instance, the Python standard library email module
          and one line of code is enough to parse a Debian 822 file fields. I doubt
          that this feature was available in the standard library when python-debian was
          started but it is here now and this vastly simplifies the code.
        
        * The focus of this library is to parse and inspect control files, not to
          emit and create them, so the code and tests can be much simpler. For instance,
          rather than using more complex case-insensitive dictionary keys while
          preserving case for Deb822-like objects, this library uses lower case keys
          throughout.
        
        * The official python-debian library is GPL-licensed making it it hard to
          combine with Apache-licensed libraries. I tried to work out a licensing
          change for python-debian with all its authors such that it
          could be integrated in permissive-licensed Python tools. Even though most
          current maintainers and contributors were OK with that relicensing to a
          permissive or an LGPL license, I could not get a reply and agreement from
          some important legacy authors: therefore the relicensing was not possible.
