The best way to keep a program properly indented (“ground”) is to use Emacs to re-indent it as you change the program. Emacs has commands to indent properly either a single line, a specified number of lines, or all of the lines inside a single parenthetical grouping.
|• Basic Indent:|
|• Multi-line Indent:||Commands to reindent many lines at once.|
|• Lisp Indent:||Specifying how each Lisp function should be indented.|
