elpa-persist 0.6.1+dfsg-2 (amd64 binary) in ubuntu oracular

 This package enables variables that persist across Emacs sessions.
 .
 The main entry point is `persist-defvar', which behaves like
 `defvar', but which persists the variables between sessions.
 Variables are automatically saved when Emacs exits.
 .
 Other useful functions are `persist-save', which saves the variable
 immediately, `persist-load', which loads the saved value, and
 `persist-reset', which resets a variable to its default value.
 .
 Each persistent variable+value pair is stored in a unique file in a
 subdirectory of 'user-emacs-directory'.
