You can run SunRav BookEditor with various parameters to configure its behavior in a more flexible way. You can see these parameters below:
BookFileName.srb - runs the program and opens the BookFileName.srb book.
/chapter chapter - opens the chapter when you open the book. It makes sense only if a filename is specified.
/tester TesterFullPath - specifies the location of tTester. For example, /tester "C:\Program Files\TestOfficePro\tTester\tester.exe"
