Summary

I'm trying to figure out how to use rebar to:

• create erlang project
• add a dependency on an erlang module from github
• start the app via the erl console
• create a release and start the app from the release (via the generated scripts)

Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

var gulp = require('gulp');
var sass = require('gulp-ruby-sass');
var concat = require('gulp-concat');
var compress = require('gulp-yuicompressor');
