If you end up using a separate config file rather than project.clj, you might
find Carica https://github.com/sonian/carica <https://github.com/sonian/carica>
useful. It allows merging config files on the classpath into one effective
config hierarchy with predictable overriding behavior.
Sample calls:
(carica/config :db) => {:classname “org.postgresql.Driver”, :subprotocol
“postgresql”, … }
(carica/config :db :classname) => “org.postgresql.Driver”
A typical use is to have a config file for a server or library in the shipped
jar file that contains defaults and a runtime classpath that allows that config
to be overridden by a config file laid down during deployment.
The deployed config file needs to contain keys for the key paths that need to
be overridden, not the entire hierarchy.
