 # backports
 This is a nixpkgs overlay that contains temporary fixes for build failures or
 other issues, usually backported from the nixpkgs master branch. Each package
-defined in this overlay shall automatically disable itself once the upstream
-package has been updated.
+defined in this overlay shall automatically disable itself once a certain
+condition is met, such as the upstream package being updated or the nixpkgs
+modification date passing a certain time.
+
+This is in place because I am extremely forgetful; I will almost certainly
+forget to undo a temporary fix later, so this takes care of it for me.
