+Due to Travis builds taking too long and timing out, the current build plan compiles and runs the tests for all exercises in a single run. This requires the following:
+
+- A master bower is given in `etc/bower.json`. Test scripts assure this one is used when they are run
+  * Please only update the master one and then run `bin/update-bower.sh` to sync them up. 
+  * After editing `etc/bower.json`, it is advisable to run `bin/check-bower.sh`. This checks for any discrepancies between various bower scripts.
+- Make sure exercises have a single module in `examples/src`
+
+See [this PR](https://github.com/exercism/purescript/pull/71) for more details and the background.
