 35.3 Saving Abbrevs in Files
 ============================
 
 A file of saved abbrev definitions is actually a file of Lisp code.  The
 abbrevs are saved in the form of a Lisp program to define the same
 abbrev tables with the same contents.  Therefore, you can load the file
 with ‘load’ (How Programs Do Loading).  However, the function
 ‘quietly-read-abbrev-file’ is provided as a more convenient interface.
 Emacs automatically calls this function at startup.
 
    User-level facilities such as ‘save-some-buffers’ can save abbrevs in
 a file automatically, under the control of variables described here.
 
  -- User Option: abbrev-file-name
      This is the default file name for reading and saving abbrevs.  By
      default, Emacs will look for ‘~/.emacs.d/abbrev_defs’, and, if not
      found, for ‘~/.abbrev_defs’; if neither file exists, Emacs will
      create ‘~/.emacs.d/abbrev_defs’.
 
  -- Function: quietly-read-abbrev-file &optional filename
      This function reads abbrev definitions from a file named FILENAME,
      previously written with ‘write-abbrev-file’.  If FILENAME is
      omitted or ‘nil’, the file specified in ‘abbrev-file-name’ is used.
 
      As the name implies, this function does not display any messages.
 
  -- User Option: save-abbrevs
      A non-‘nil’ value for ‘save-abbrevs’ means that Emacs should offer
      to save abbrevs (if any have changed) when files are saved.  If the
      value is ‘silently’, Emacs saves the abbrevs without asking the
      user.  ‘abbrev-file-name’ specifies the file to save the abbrevs
      in.  The default value is ‘t’.
 
  -- Variable: abbrevs-changed
      This variable is set non-‘nil’ by defining or altering any abbrevs
      (except system abbrevs).  This serves as a flag for various Emacs
      commands to offer to save your abbrevs.
 
  -- Command: write-abbrev-file &optional filename
      Save all abbrev definitions (except system abbrevs), for all abbrev
      tables listed in ‘abbrev-table-name-list’, in the file FILENAME, in
      the form of a Lisp program that when loaded will define the same
      abbrevs.  If FILENAME is ‘nil’ or omitted, ‘abbrev-file-name’ is
      used.  This function returns ‘nil’.
