+Optional arg OP1 is an alternate form for OPERATION if there is
+ only one file.
+Optional arg HOW-TO is used to set the value of the into-dir variable
+ which determines how to treat target.
+ If into-dir is set to nil then target is not regarded as a directory,
+ there must be exactly one marked file, else error.
+ Else if into-dir is set to a list, then target is a generalized
+ directory (e.g. some sort of archive). The first element of into-dir
+ must be a function with at least four arguments:
+ operation as OPERATION above.
+ rfn-list a list of the relative names for the marked files.
+ fn-list a list of the absolute names for the marked files.
+ target.
+ The rest of into-dir are optional arguments.
+ Else into-dir is not a list. Target is a directory.
+ The marked file(s) are created inside the target directory.
+
+ If HOW-TO is not given (or nil), then into-dir is set to true if
+ target is a directory and otherwise to nil.
+ Else if HOW-TO is t, then into-dir is set to nil.
+ Else HOW-TO is assumed to be a function of one argument, target,
+ that looks at target and returns a value for the into-dir
+ variable. The function `dired-into-dir-with-symlinks' is provided
+ for the case (common when creating symlinks) that symbolic
+ links to directories are not to be considered as directories
+ (as `file-directory-p' would if HOW-TO had been nil)."
