[erlang-questions] "Automatic" recompile app from a console

[John Kemp]

Hi,

I have been writing an application using rebar to build the app. I run 
the server and open a console. I then change the source code and 
apparently I need to leave the console, 'make rel' and restart the app 
and the console.

I'm sure there's a better way to do what I'm doing.

One project I found is https://github.com/rustyio/sync, but this did not 
(yet) work for me according to the instructions.

How can I have my rebar (or just Erlang) app automatically recompile 
('make rel') when one of the source files changes, or run a command from 
within the console to do this?

Cheers,

JohnK
