+A tool to convert triples from SDB to TDB.
+
+Unlike the RDF-migration tool, this tool is not tied to the VIVO
+properties files. Instead, you must provide:
+* The URL for the SDB, including username and password parameters
+* The directory path for the TDB. 
+     The directory must exist. 
+     The directory must be empty, unless the "force" optiopn is used.
+
+Examples:
+
+   java -jar sdb2tdb.jar \ 
+   		jdbc:mysql://localhost/vitrodb?user=vivoUser&password=vivoPass \ 
+   		/usr/local/my/tdb
+   		
+   java -Xms512m -Xmx4096m -jar .work/sdb2tdb.jar \
+        'jdbc:mysql://localhost/weill17?user=vivoUser&password=vivoPass' \
+         /Users/jeb228/Testing/instances/weill-develop/vivo_home/contentTdb \
