Well, now it is my turn to be confused:  what *is* the intended 
difference between board and target?

I think I have a rough idea:  boards are semi-generic hardware profiles 
while a "target" is a specific instance of a "board", although for some 
tests (such as compiler tests) the same physical machine may be 
represented as multiple targets, with varying compiler options.  Or in 
other terms, a "board" name is a model number, while a "target" name is 
a hostname.  Is this correct?

In particular, do I correctly understand that the set of available 
boards and targets is a characteristic of a testing lab rather than of a 
(portable) testsuite?

I am trying to make a clean distinction between "Customizing DejaGnu" 
(adapting DejaGnu to a particular testing lab) and "Extending DejaGnu" 
(adding testsuites, tools, tests, etc.).  Essentially, everything needed 
to run existing tests in a new environment fits in the "Customizing 
DejaGnu" chapter, while the step-by-step procedures for adding new 
tests/tools/testsuites fit in the "Extending DejaGnu" chapter.  A new 
chapter (tentatively titled "DejaGnu Testsuite Layout") will explain 
what goes where in a DejaGnu testsuite.
