This is a handy bit of code I've written more than once. I thought I'd throw it in here so I can refer back to it later. Basically, it lets you read a config file to produce a Clojure map. The config files themselves can contain one or more forms, each of which can be either a map or a list. Maps are simply merged. Lists correspond to invocations of extension points, which in turn produces a map, which is merged along with everything else.
Consider the following files:

| # Hello! This is a micro-post about how to produce native executables | |
| # from ClojureScript source. The basic idea is to produce a | |
| # JavaScript file using the ClojureScript compiler, and then use a | |
| # Node.js tool called nexe (https://github.com/jaredallard/nexe) to | |
| # compile that into an executable. The resulting file can be run | |
| # without requiring a node install on the target machine, which can | |
| # be handy. |
