I would take one step back, and suggest that if any project has as many 
scripts as this one, it should be put in an R package.  You can 
distribute that by building it into a tar.gz file and putting that 
single file in a place where people can download it.  Github and R-forge 
work well for packages, and I assume other hosting services do too, 
though I haven't used many.

People seem to be unreasonably reluctant to put their code into packages.

I've created a git repository
at?https://sourceforge.net/p/rhelp/code/ci/master/tree/.? I've used git
before, so that's what I chose.? I had forgotten that sourceforge didn't
have a download all files command.? I don't post files often.

About the semantics of "crash":? Perhaps I'm showing my age here.?
It used to be that programs crashed, bombed, etc. when they hit unanticipated
errors.? These programs lived in a OS without an intermediary.? Now, we have
programs of programs running within multiple applications on multiple servers
with multiple OSs.? Since I'm not a programmer by profession, I've had
little need to use these constructs.
