Cannot merge SIS-files with embedded SIS-files (or more specifically PIPS.SIS)

What steps will reproduce the problem?
1. Run ensymble/mergesis with PIPS.SIS, for example:

python.exe ensymble.py mergesis --cert="xxx.cer" --privkey="yyy.key" my_app.sis 
Python_2.0.0.sis pips.sis release_with_all_components.sis

2. Error message: 

ensymble.py: pips.sis: input SIS file contains embedded SIS files

What is the expected output? What do you see instead?
- I would like the program to produce a SIS with PIPS.SIS included

What version of the product are you using? On what operating system?
- Ensymble v0.28 2009-01-30
- on Windows with Python 2.5.4

Please provide any additional information below.
- PIPS.SIS is needed in all S60 devices before 3rd ed FP2, so being able to 
merge it into a single installation file with an application would be a big 
thing for everyone releasing PyS60 software.
