Create related links to external files or web sites
This procedure uses a text editor to put a series of links to related topics on remote systems or to files outside the repository.
You can make related links to websites and FTP locations, as well as to files outside the repository.
When you are linking to files you may use either absolute or relative pathnames. However, you should keep in mind that setups vary in different machines. You can safely use relative pathnames if you are sure that multiple documents will always be sent as a single package. However, if there’s a chance that only a portion of the files will be sent, and that the target file isn’t among them, then the link may become invalid.
