+Configuration profiles
+----------------------
+Even though the applications don't directly support configuration profiles,
+they conform to the XDG standard, and thus you can change the location they
+load configuration from via XDG_CONFIG_HOME (normally '~/.config') and the
+location where store their data via XDG_DATA_HOME (normally '~/.local/share').
+
+It would be relatively easy to make the applications assume whatever name you
+run them under (for example by using symbolic links), and load different
+configurations accordingly, but I consider it rather messy and unnecessary.
