native overburning in os x

problem:
You have object(s) over 700mb you want to burn in os x, using Finder, on a 700mb CD-R

impact:
You can't burn it, Finder tells you you need larger media

solution:
For a slightly oversized dataset, say 710mb you can use overburning technique. This is a common feature of 3rd party burning tools/software. Here is a command line solution:

Create a set of folders and a shell script to suit, with the following contents:

hdiutil makehybrid -o tempfile contents_to_overburn/
hdiutil burn tempfile.iso
rm tempfile.iso
rm contents_to_overburn/*
