+"""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
