Options set using environment variables
---------------------------------------

The following environment variables affect operation of the
tests. Under most circumstances they should not be set, allowing the
tests to use default values. A full description of what all of them
do is beyond the scope of this README. If you need the degree of
customisation that they offer, you should be able to read the code in
SATest.pm to see how they are used.

See the following sections for customisations that may be required in common
configurations.  All the variables are listed here to document which may
conflict with the regression tests if they happen to be set to arbitrary
values.
