config      Lists all forever user configuration
set <key> <val>            Sets the specified forever config <key>
clear <key>                  Clears the specified forever config <key>
logs                                Lists log files for all forever processes
logs <script|index>      Tails the logs for <script|index>

-c       COMMAND      COMMAND to execute (defaults to node)
-a, --append      Append logs
-f, --fifo      Stream logs to stdout
-n, --number      Number of log lines to print

e.g. forever start --uid "production" app.js
forever stop production
--sourceDir      The source directory for which SCRIPT is relative to
--workingDir      The working directory in which SCRIPT will execute
--minUptime      Minimum uptime (millis) for a script to not be considered "spinning"

-h, --help You're staring at it

[Long Running Process]
The forever process will continue to run outputting log messages to the console.
ex. forever -o out.log -e err.log my-script.js

The forever process will run as a daemon which will make the target process start
in the background. This is extremely useful for remote starting simple node.js scripts
without using nohup. It is recommended to run start with -o -l, & -e.
ex. forever start -l forever.log -o out.log -e err.log my-daemon.js
forever stop my-daemon.js
