title: Dropbox selective syncing - pattern matching?
body: <p>I'm using Dropbox on daily basis and put my programming projects in there.
  It works great, but once I got many projects my <code>/node_modules</code> dir's are putting 
  a struggle on Dropbox. It's syncing process starts to be slow and it eats up CPU time.</p>
  
  <p>Is there any way to do a selective sync based on directory name or a mask pattern?
  Would be nice to have to a <code>.gitignore</code> equivalent to configure.</p>
  
  <p>Any 3rd party software for that task?</p>
