"""Script to synchronize two source trees.

Invoke with two arguments:

python treesync.py slave master

The assumption is that "master" contains CVS administration while
slave doesn't.  All files in the slave tree that have a CVS/Entries
entry in the master tree are synchronized.  This means:

If the files differ:
        if the slave file is newer:
            normalize the slave file
            if the files still differ:
                copy the slave to the master
        else (the master is newer):
            copy the master to the slave

normalizing the slave means replacing CRLF with LF when the master
    doesn't use CRLF
