Re: Cygwin V1.0 CD license?

Ok. I figured that but this was not clear at all on the Red Hat 
pages. It would be nice if a link to the actual license text was 
included on the Red Hat info pages for the 1.0 CD-ROM release.

Ok great.

Ok. So if I built an EXE file with Cygwin that was based on MPL 
sources, I can distribute the product so long as I do the following:

 1. Include binaries for the EXE file
 2. Include the MPL'ed sources for the EXE file
 3. Include the cygwin1.dll 
 4. Include sources for the cygwin1.dll itself.

One point of contention would be that the MPL does not require 
distribution of the sources with a project, so long as the code is 
available by an accepted means of electronic distribution (ie: tar.gz 
files on an ftp/web server, CVS etc).

Would using Cygwin require this to be changed so that the sources are 
included with the EXE, or would only the sources to the cygwin1.dll 
be required to be distributed?
