problem in understanding

[Mj_Developer]

I cannot understand the bold sections of following paragraph. Please help me.

Currently ADL can only certify Learning Management Systems and Content Packages. There is no procedure for certifying tools. The closest you could get would be to create elaborate content packages from your tools and show those off as certified products from your tools, but the tools themselves cannot be certified. The reasoning is that procedures for LMSs and Content Packages have been vetted and "fool proofed", but tools are dynamic so that a common procedure cannot be created. There is also the argument that most tools CAN create conformant content, but they don't automatically, that the user can somehow break it. At that point we would be trying to certify a tool and a process for using that tool, which just gets messy.

vetted and "fool proofed" = tested and made as perfectly workable as possible.
argument = point
can somehow break it = can break the tool in some way
gets messy = becomes complex, difficult or impossible

Please rephrase the following sentence since I cannot understand it:
