=== Q. Why does Fuego use shell scripting as the language for tests? ===
There are other computer languages which have more advanced features
(such as data structions, object orientation, rich libraries, concurrency,
etc.) than shell scripting.  It might seem odd that shell scripting was
chosen as the language for implementing the base scripts for the tests in
fuego, given the availability of these other languages.

The Fuego architecture is specifically geared toward host/target testing.
In particular, tests often perform a variety of operations on the target in
addition to the operations that are performed on the host.
When the base script for a test runs on the host machine, portions of the
test are invoked on the target.  It is still true today that the most common
execution environment (besides native code) that is available on almost
every embedded Linux system is a POSIX-compliant shell.  Even devices with very
tight memory requirements usually have a busybox 'ash' shell available.

In order to keep the base script consistent, Fuego uses shell scripting on
both the host and target systems.  Shell operations are performed on the target
using 'cmd', 'report' and 'report_append' functions provided by Fuego.

Note that Fuego officially use 'bash' as the shell on the host, but does not 
require a particular shell implementatio to be available on the target.
Therefore, it is important to use only POSIX-compatible shell features for
those aspects of the test that run on target.
