+Subject: [PATCH 1/1] scripts/pyzor: undo ConfigParser python-3.x
+ compatibility.
+
+The build system for pyzor-1.0.0 still runs the 2to3 utility on the
+scripts to be installed. As an unintended side-effect, the python-3.x
+"try... import... except" compatibility block for the ConfigParser <->
+configparser module gets modified (the module name gets mistakenly
+lowercased).
+
+This commit puts back the python-2.x "import ConfigParser" line
+unconditionally, and we'll have to rely on 2to3 to fix it when run
+under python-3.x. In newer versions of pyzor, the automatic 2to3 will
+not happen.
+
+Bug: https://bugs.gentoo.org/643692
