;; - localname is a string. This are temporary properties, which are
;; related to the file localname is referring to. Examples:
-;; "file-exists-p" is t or nile, depending on the file existence, or
+;; "file-exists-p" is t or nil, depending on the file existence, or
;; "file-attributes" caches the result of the function
-;; `file-attributes'.
+;; `file-attributes'. These entries have a timestamp, and they
+;; expire after `remote-file-name-inhibit-cache' seconds if this
+;; variable is set.

;; - The key is a process. This are temporary properties related to
;; an open connection. Examples: "scripts" keeps shell script
Every entry has the form (REGEXP PROPERTY VALUE). The regexp
matches remote file names. It can be nil. PROPERTY is a string,
and VALUE the corresponding value. They are used, if there is no
-matching entry in for PROPERTY in `tramp-cache-data'."
+matching entry for PROPERTY in `tramp-cache-data'."
