On my current project we decided to use the formatting provided by
GLIDE/GPS and to use the -gnaty switch to check it. You can give a
whole slew of options to -gnaty but it seems far easier to just accept
the defaults even if they aren't what you would be used to. The 3
space indent is a case in point; of course if your editor just does it
for you it's not so hard to accept!

What always baffles me is how people will *not* train themselves to do
what the style checker expects, and will *not* just fix the style
warnings as they go.
