jgit merge question

Hi all,

My apologies in advance for the newbie question, and I hope this is  
the correct forum - please let me know if there is a better place.

I have been working with the JGit library and with the pgm files and  
other documentation I have been able to implement most of the basic  
functions that I need for my testing application - including fetch.   
This is great!  However, I have not been able to successfully  
implement the merge function with JGit.  There is some reference to  
this in the mail archive, but I cannot find any of the merge code that  
is referenced in the distribution.  I have tried to pull from  
pgm.MergeBase.java, but that hasn't been successful.

My question:
Is there any sort of tutorial or reference code snippet that  
implements merge?  Or is there a trick to getting the MergeBase code  
to achieve a basic merge?

Thanks in advance!

Best,
David
