The sugarize library (which is Albert's originally, catmoran just  
bundled it with my shell script to be easier to use) does nothing  
about the Journal. It only makes sure a proper icon is shown in the  
frame.

You will have to do the Journal integration yourself. An example of  
this was discussed in the "Journal integration for Scratch" thread.

Besides, if you indeed write the activity yourself in C++ there is no  
need to use the sugarize library in the first place. This was made  
purely to sugarize existing apps, and is rather insufficient for  
proper activities.

What for?

It is not reasonable to assume this.

Looking at your script it hard-codes the path to your activity bundle.  
This is not good practice and not necessary either. Please refer to  
the original of the script:

http://lists.laptop.org/pipermail/devel/2008-January/009387.html

and also it seems like a good idea for you to read

http://wiki.laptop.org/go/Low-level_Activity_API

which describes to the best of my knowledge what an activity author  
needs to do if she is not using the Python activity toolkit.
