- Use Python 3.
- Switch to gobject-introspection and other more maintained libraries
(vs PyGTK).
- Use `fetchFromGitLab`.
- Replace the non absolute paths fix in `xlib.py` with
`substituteInPlace`.
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
