[dev] Transplanting CK-ERP to the Horde Framework

[C K Wu]

Hi, everyone,

If the caption subject is off-topic, please redirect me to the 
appropriate list and thank you in advance.

I am the developer of CK-ERP, which is a 3rd party accounting/ERP/CRM 
add-on that runs on top of phpGroupWare.  Recently, I had a problem with 
the Free Software Foundation (FSF), saying that one of the licensing 
term of CK-ERP being not GPL compliant.  With phpGroupWare being mostly 
GPL licensed, FSF indicated that CK-ERP must be GPL'ed too.  While I 
don't agree with FSF's conclusion, I don't wish to engage in a 
protracted argument with FSF, so I am trying to find a new home for CK-ERP.

One of the complication with the whole thing is that CK-ERP is designed 
to communicate with phpGroupWare via API calls and at the same time, 
phpGroupWare's API (phpgwapi) is issued under LGPL, so CK-ERP should be 
well protected against any GPL requirement.  However, one key 
phpGroupWare developers claim that while phpgwapi is under LGPL, some of 
its code actually calls on other GPL module/codes, causing FSF to 
conclude that the LGPL protection is ineffective.  Therefore, while 
Horde Framework 3 fits perfectly as a new platform for CK-ERP to run on, 
I am still a bit hesitant.

Perhaps, developers here could confirm if the Horde Framework 3 is fully 
LGPL'ed and that the Framework does not in term call up other GPL code. 
  Once I have the confirmation on this, I'll start planning the transplant.

For a demo of CK-ERP, please refer to http://ck-erp.sourceforge.net

Cheers,
CK
