+;; Emacs is an extensible, customizable, free/libre text editor.  It
+;; allows specification of certain settings that will be applied to
+;; all files in current directory and its subdirectories. This is

+;; for all contributors of Gnuastro, like the maximum length of lines
+;; or the number of spaces to be used for indentation.
