title: Is it possible to change argv or do I need to create an adjusted copy of it?
body: <p>My application has potentially a huge number of arguments passed in and I want to avoid the memory of hit duplicating the arguments into a filtered list.  I would like to filter them in place but I am pretty sure that messing with argv array itself, or any of the data it points to, is probably not advisable.  Any suggestions?</p>
