     * ``CALIBRE_TEMP_DIR`` - sets the temporary folder used by calibre
     * ``CALIBRE_CACHE_DIRECTORY`` - sets the folder calibre uses to cache persistent data between sessions
     * ``CALIBRE_OVERRIDE_DATABASE_PATH`` - allows you to specify the full path to metadata.db. Using this variable you can have metadata.db be in a location other than the library folder. Useful if your library folder is on a networked drive that does not support file locking.
-    * ``CALIBRE_DEVELOP_FROM`` - Used to run from a calibre development environment. See :ref:`develop`.
-    * ``CALIBRE_OVERRIDE_LANG`` - Used to force the language used by the interface (ISO 639 language code)
-    * ``CALIBRE_TEST_TRANSLATION`` - Used to test a translation .po file (should be the path to the .po file)
-    * ``CALIBRE_NO_NATIVE_FILEDIALOGS`` - Causes calibre to not use native file dialogs for selecting files/folders.
-    * ``CALIBRE_NO_NATIVE_MENUBAR`` - Causes calibre to not create a native (global) menu on Ubuntu Unity and similar linux desktop environments. The menu is instead placed inside the window, as is traditional.

+    * ``CALIBRE_USE_SYSTEM_THEME`` - by default, on Linux, calibre uses its own
       builtin Qt style. This is to avoid crashes and hangs caused by incompatibilities
       between the version of Qt calibre is built against and the system Qt. The
       downside is that calibre may not follow the system look and feel. If
       you set this environment variable on Linux, it will cause calibre to use
       the system theme -- beware of crashes and hangs.
-    * ``CALIBRE_SHOW_DEPRECATION_WARNINGS`` - Causes calibre to print deprecation warnings to stdout. Useful for calibre developers.
-    * ``CALIBRE_NO_DEFAULT_PROGRAMS`` - Prevent calibre from automatically registering the filetypes it is capable of handling with Windows.
-    * ``CALIBRE_USE_DARK_PALETTE`` - Set it to ``1`` to have calibre use dark colors and ``0`` for normal colors (ignored on macOS).

       On Windows 10 in the absence of this variable, the Windows system preference for dark colors is used.
