Applying Python To Modify Java Code

Python script intended to open each Java's project file, add the license term on the start of the file as a Java comment and writing it to the disk.

1) You'll need a Python interpreter. Check this out in http://python.org.
2) You'll need to enter the root file directory of the Java project, like 
python AddLicense.py ${path}
 where ${path} defines user project root directory.
3) See http://fcmanager.wiki.sourceforge.net
