In (info "(elisp) Auto Major Mode"), there is an example of how to prepend several pattern pairs to `auto-mode-alist':
(setq auto-mode-alist
(append
;; File name (within directory) starts with a dot.
'(("/\\.[^/]*\\'" . fundamental-mode)
;; File name has no dot.
("/[^\\./]*\\'" . fundamental-mode)
...)
auto-mode-alist))
I'm confused about the first "/" in the two regular expressions. Why is there a slash character? Can anybody help? Thanks.

It's for a file name "within [a] directory", e.g., /foobar.
The / is the directory separator.
