+### Reducing startup time with skip-macros
+
+If you run your script with the property `clojure.spec.skip-macros=true` you get significant 
+savings:
+
+		time clj -J-Dclojure.spec.skip-macros=true -m recap sv
+		real	0m2.587s - user	0m6.997 - sys	0m0.332s
+
+Versus the default:
+
+		time clj -J-Dclojure.spec.skip-macros=false -m recap sv
+		real	0m3.141s -user	0m8.707s -sys	0m0.391s
+
+So that's like half a second for free on my machine.

+### Capturing current version
 
 If you would like to capture the build environment at compile time (e.g. the exact GIT revision, or when/where 
 the program was built, or the version of your project as defined in `project.clj`) so you can print
