It revealed a regression - return code not the same as v2.x for invalid PDF/A. It's also not easy to get the return code out of ruffus. Will need to tweak the final step of the pipeline.

For testing PDF/A generation failures, this wrapper calls ghostscript

It assumes that it is called from a staged system PATH where the first
|
|
item on the PATH contains a file named 'gs' which is a symlink to this
|
|
file. It will strip out the first item on path to invoke the real
|

'gs'.
