ClientUser::Diff( FileSys , FileSys , FileSys , int, char , Error * )

Diff two files, and output the results to a third file.

Virtual?	Yes
Class	`ClientUser`
Arguments	`FileSys *f1`	the first file to be diffed
	`FileSys *f2`	the second file to be diffed
	`FileSys *fout`	the target file for diff output
	`int doPage`	should output be paged?
	`char *diffFlags`	flags to diff routine
	`Error *e`	an `Error` object
Returns	`void`

Notes

This method works like Diff(), but instead of sending data to the standard output, writes the data to the specified output file.
