Hello Corinna,

Thank you for the prompt reply. I'm still a little confused.

1) Licensing. Could you please explain what "linking against Cygwin" means? I'm guessing that is for trying to port a Unix application to Windows? We're just wanting to use a few of the open-source tools (grep, find, ghostscript, etc.), so I'm guessing we do *not* need to purchase a special license, but we just want to be sure.

2) Installer. We could use some specifics on how to comply with the cygwin lincensing.

I think ideally our product would have a single installer that includes our closed-source product, whatever open-source cygwin tools our product relies on, and the full sources of cygwin. How exactly do we include the proper cygwin files? If we do a sample cygwin install on a PC, does the cygwin folder conatin everything we need (open-source tools + cygwin source), or is it more complicated than that?

Regards,
Sean
