Most of us have our own little aliases or bash scripts to quickly switch
between stack versions/trunk/etc.  Since the "optimal" approach is very
dependent on the individual's situation and preferences, we have yet to come
up with anything one-size-fits-all.  For example, the script I've attached
that I and a few other WGers use is probably not nearly as useful if you're
not developing on low-level stacks.

It has a couple hard-coded paths, but they're towards the top of the file.
An example workflow:

dev visualization-1.0 visualization_common                   # set the
package path to include the <base>/dev/visualization-1.0 and
<base>/dev/visualization_common paths, in addition to my "base" installed
stacks
dev -a geometry-1.0
# add the <base>/dev/geometry-1.0 stack to my package path
dev
-s
# save my state, next time I open a shell it will have my current
preferences

Again, this is just one way of doing it, though I find it's the best out of
all I've tried for my situation (working on ROS core as well as some of the
lower-level stacks).  Other people keep fully separate trees for different
situations, or separate overlay setup.sh files, or other things I haven't
guessed at.

If all you want is boxturtle vs. latest, setting up those aliases or
overlays is much easier.
