Neither the compiler nor the source code is included in any(almost - 
except when we use yaws) system we produce. Our test team don't like us 
changing modules in the test installation (understandably) - so 
troubleshooting becomes a bit of a hassle. Typically, this is what I 
have to do if I want to troubleshoot in the testplant.

1. Take a backup of the existing module
2. Compile correct version of module with +export_all option
3. FTP to testplant (sometimes via two hops because security folks are 
sometimes Business Prevention Officers)
4. Load new module
5. Do stuff
6. Backout the patch

It'll be nice to be able to just do this.

5. Do stuff.

Well, when there are 15 different services live and 40 erlang nodes to 
support each with different versions of software, it is easier said 
than done.
