This little script checks out the last tag -- the thing is, that will get the tag most recently created, but who knows if it's the best tag to be building.

for x in *
do
if [[ -d $x ]]
then cd $x
echo -n "$x "
rev="$(git tag | tail -1)"
if [[ ! -z "${rev}" ]]
then
git checkout "${rev}"
fi
cd - > /dev/null 2>&1
fi

By the way, my notes on the current (as of Jan 9 2018) modules
Build failures with the master branch checked out: AudibleInstruments Autodafe Befaco Fundamental VCVRack-Simple RJModules trowaSoft-VCV

The following tags fix most of them. VCVRack-Simple probably builds with GCC version greater than 4.8.5

AudibleInstruments: v0.5.0
Autodafe: broke -- not compatible with Rack 0.5.1 API
Befaco: v0.5.0
Fundamental: v0.5.1
VCVRack-Simple: can't compile with gcc 4.8.5
RJModules: 0.5.0
trowasoft-VCV: v0.5.5

LOL ... "MSM v0.3.2" ..this isnt my latest version.. its 0.5.5

Sure@Phal-anx -- my understanding of how this all works is evolving.
