Create a symbolic link to add directories to Dropbox

OS X and Linux users of Dropbox will appreciate this tip that adds links to directories outside of the default Dropbox folder for backups:

Terminal Time:
:: Fire up the Terminal
:: Type “ln -s /path/to/desired-folder ~/Dropbox/desired-folder” making the appropriate substitutions and not including the quotation marks
:: Hit Return
This works with individual files as well using:
:: Start a Terminal session
:: “ln -s /path/to/desired-file ~/Dropbox/desired-file”
:: Enter

Quick Terminal Tip:
:: Begin the command by typing “ln -s” (don't hit Return just yet)
:: From the Finder/File Chooser drag the folder/file that you want to link into the Terminal window
:: Complete the rest of the line with ~/Dropbox/desired-file and hit Return

Note that an Alias file or folder does not work with Dropbox. Not sure why, but creating the symbolic link takes care of the problem.
