-ibatis2mybatis
-==============
+The tool is designed around an xslt transformation and some text replacements packaged in an ant task and tries to deliver a good starting point before the more complex work begins.
+
+Usage:
+Put Your old ibatis2 sqlmap files in the source folder and execute the ant build file.
+The task converts Your sqlmap2 files to myBatis mappers in the destination folder and reports anything it cannot convert in the console.
+
+Have fun and maybe You can post some improvements/bugfixes as this initial version is by no means perfect yet!
