AED_Tools is the prefered starting point for downloading source trees for AED projects. It contains fetch_sources scripts for Unix based (Linux/Mac) or windows to download or update Source trees for GLM, libfvaed2 and libaed2. There are also some useful scripts in admin to help track changes.
AED_Tools_Private is like AED_Tools but for AED internal use - it also has support for the "plus" versions of our software and limited support for building TuflowFV.
NB: fetch will only work if you have set up github's security requirement in terms of an ssh key.
