External programs can be used to load and store data. Loading is done by calling the program, redirecting its output to a file and loading the file. Saving is done by saving to a temporary file and calling the external program which reads the file from stdin.

As a trivial example, cat can be used to load local files. As a more useful example, httpget can be used to load a file from a web server.
