There are two ways to specify file local variable values: in the
first line, or with a local variables list. Here's how to
specify them in the first line: -*- mode: modename; var: value;
... -*- You can specify any number of variable/value pairs in
this way, each pair with a colon and semicolon. The special
variable/value pair ;, if present, specifies a major mode. The
values are used literally, and not evaluated. You can use M-x
add-file-local-variable-prop-line instead of adding entries by
hand. This command prompts for a variable and value, and adds
them to the first line in the appropriate way. M-x delete-file-
local-variable-prop-line prompts for a variable, and deletes its
entry from the line. The command M-x copy-dir-locals-to-file-
locals-prop-line copies the current directory-local variables to
the first line (see Directory Variables). Here is an example
first line that specifies Lisp mode and sets two variables with
numeric values: ;; -*- mode: Lisp; fill-column: 75; comment-
column: 50; -*- mode, othe
