SYNOPSIS
        int copy_file(string from, string to)

DESCRIPTION
        The efun copy_file() will copy the file <from> to the new name <to>.
        If <to> exists and is a directory, then <from> will be placed in that
        directory and keep its original name.

        You must have read permission for <from> and write permission for
        the target file to copy the file.

        On successfull completion copy_file() will return 0. If any error
        occurs, a non-zero value is returned.

EXAMPLE
        copy_file("/players/wizard/obj.c", "/players/wizard/newobj.c");

HISTORY
        LDMud 3.2.9 restricted the error behaviour to returning non-0.
