Comment (by rhaas):

 Well. Yes and no. It works as well as the PETSc equivalent, which I always
 found to be lacking, in that it outputs the error after the fact.
 Eg.
 {{{
 sim create --queue development foo --configuration sim --parfile foo.bar
 --procs 156 --num-threads 6 --walltime 0:10:00
 }}}
 will result in simfactory creating the simulation and then complaining
 {{{
 Error: Command line option(s) '--procs,--walltime,--queue,--num-threads'
 were not used. Most likely 'create' does not support them.
 }}}
 On the other hand doing something like {{{sim show-output --follow foo}}}
 after foo has finished will complain about {{{--follow}}} not being used
 since simfactory only considers this option while a simulation is running.
 The SpEC (which uses the same system) way of dealing with this is to
 request these unused options anyway to pacify the OptionsParser. So maybe
 a warning woud be more appropriate though warnings seem to be only output
 when run with --verbose, yes?
 There are ways to get to options that would not be caught (access to the
 raw option string is possible) and while I would expect that no well
 behaved routine does that, I have no idea of how simfactory behaves
 internally.
