git notes for dal in submodule

[Tim Richardson]

Hi. I think some tips on migrating git repositories to the submodule may be appreciated. 

I think this is the idea:

to clone the repository
git clone --recursive ...

to update an existing repository:

git submodule init
git submodule update
rm -r gluon/dal

is the last step going to be always necessary?

 I have not used submodule before and my git is always just enough to get by, so I don't understand why gluon/dal is still in master.

the last step is only due once, for people having "the old structure" after pulling the new one

why can't that directory be deleted in master?  

[Niphlod]

master hasn't it. it's the local copy that holds it because empty dirs are not removed when you untrack-->delete all files within in git.
