/* Author: Alessandro Pellegrini <alessandro.pellegrini@tin.it>
* This class posts a Birthday Thank you on your Facebook wall
* You must donwload Facebook4J for this to work.
* Before running this script, log in to Facebook!
* You must configure static variables in the class for it to work correctly!
* Compile with:
* javac -cp facebook4j-core-2.0.4.jar BirthdayThanks.java
* Run with (on Windows):
* java -cp facebook4j-core-2.0.4.jar;. BirthdayThanks
* Check if the Facebook4J core jar has the correct name!
* There is a dryRun flag which prevents the program from actually posting
* to your Facebook wall. Set it to false after having tried its behaviour!
* ...and Happy Birthday! :)
