Config File Settings
~~~~~~~~~~~~~~~~~~~~

Settings in megatest.config

Config File Additional Features
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Including output from a script as if it was inline to the config file:

-------------------------
[scriptinc myscript.sh]
-------------------------

If the script outputs:

-------------------------
[items]
A a b c
B d e f
-------------------------

Then the config file would effectively appear to contain an items section
exactly like the output from the script. This is extremely useful when
dynamically creating items, itemstables and other config structures. You can
see the expansion of the call by looking in the cached files (look in your
linktree for megatest.config and runconfigs.config cache files and in your
test run areas for the expanded and cached testconfig).

Disk Space Checks
^^^^^^^^^^^^^^^^^

Some parameters you can put in the [setup] section of megatest.config:
