Best way to track and isolate project dependencies?

[Lassi Kortela]

Does Chicken support installing eggs into a project-specific directory, 
and using only those eggs for that project (ignoring system-wide ones)? 
I.e. something like Python's venv 
(https://docs.python.org/3/library/venv.html) and similar tools for 
other languages.

General-purpose libraries are shipped as eggs, which can depend on other 
eggs. Is the eggs facility intended only for these public libraries, or 
can it be used to track the dependencies of an application in 
development as well?
