+ The move task, as it is now, copies the source file to the destination and then 
+ deletes the source. 
+ 
+ Two issues:
+ 
+ 1.  Copying is done even when the canonical file names are identical.  This 
+ mustn't be done.
+ 2.  Deletion is performed unconditionally resulting in deletion of the 
+ destination file (which happens to be the same as the source, in this case).
+ 
+ In contrast, the copy task checks to see if the source and destination file 
+ names are the same and then skips copying it if they are.  
+ 
+ The Move task should either skip over the file quietly (as Ren does in Windows) 
+ or fail out saying the source and destination files are identical (as mv does 
+ in Unix)
+ 
+ I am marking it as a minor issue as I don't think users would be performing 
+ moves where the source and destination are the same.  But still, users will be  
+ users...
+ 
+ Sample:
+ 
+ Assuming file f1 is already in /export/home/mumasank, execution of the 
+ following task results in f1 being deleted.
+ 
+    <target name="move2samefile">
+       <move file="f1" tofile="../../home/mumasank/f1"/>
+    </target>
