Dropipe is a Mac OS droplet to where you can drag files to upload to a TarPipe workflow. Just open the DMG and drag it to your application folder (and from then to the dock) or to the desktop, according to your preferences.
This product is under the AWL and you should take that into consideration before using it.
Note: The token is kept inside the Dropipe.app, so if you want to have two instances of Dropipe for different workflows, just copy and paste (and rename it if you want). To reset the token, just delete Dropipe.app/Contents/token.txt.
