Re: [nant-dev] Adding an update parameter to the <zip> task

[Dominik G. <os...@gu...>]

Hi,

my understanding is that the use of Dotnetzip should be possible as long 
as we provide it in binary form. This should be ok with Gpl2, but our 
license also includes "any later" GPL which means that we also need to 
take Gpl3 into account. And therefore I don't have any glue if MS-PL 
fits or not.

But if I remember correctly we had some discussions regarding source of 
nunit and ndoc and why we don't provide it in out repository. @Ryan Do 
you remember?


Maybe we should ask Cheeso for clarification

just my 2 ct.

Dominik
