forever watch file + multiple directories (using a watchIgnore glob)

kick

forever start --uid 'appname' -o app.log -e error.log -a -w --watchIgnore '!{app.js,{src,common,lib}/**}' app

#   breaking it down:
#
#   --uid 'appname'                                 name the process so we can use `forever stop appname`.  
#                                                   the quotes are necessary.
#
#   -o app.log / -e error.log                       pipe stdout/stderr to files
#
#   -a                                              append to said files
#
#   -w                                              watch the current directory for changes
#
#   --watchIgnore '!{app.js,{src,common,lib}/**}'   tell forever to ignore changes from files that do NOT match 
#                                                   the pattern `{app.js,{src,common,lib}/**}`. The `!` negates
#                                                   the glob, so we use the double negative to only watch
#                                                   specific files.  This particular pattern results in the app
#                                                   restarting when app.js or any file within src/, common/, 
#                                                   or lib/ is modified.
#                                                   
#    app                                            the main file to run: app.js
