Map Slicing Tool doesn't load correctly..

[dave204]

I have imported Map Slicing Tool into the Workspace under the General tab as Existing code on Eclipse.
2 issues: Yhere are 3 errors in the main Java file (one appears to be related to the copyright being placed at the top of file, instead of expected "com.example etc package name"..
Secondly, how do I run it as an Eclipse Application" - there is only Run as Java Application - which says missing main file???
Could anyone please explain why this is so, the errors, when I have clearly followed instructions??
Did anyone at Lemberg try out their own depository??
