Hello, I have a feature request/question for the cygport maintainer (not 
sure how those are normally handled)

cygport reports the required packages, but only after building the 
application.

My workflow is normally the following one:

Setup the cygwin environment for building and testing, download the 
sources, then in an offline environment, build and test.

Since "cygport cmus all" reports the required dependencies only after 
building, I have some difficulties in taking advantage of the listed 
packages...

I could imagine to have a "minimal cygwin environment" for executing 
"cygport cmus enlist-dependencies", and from the output create one 
cygwin environment for building, and one for testing, but if it needs to 
build the application, I do not see how to use it for bootstrapping an 
offline environment.

I could move the REQUIRES from the cygport file to somewhere else and 
use it only myself, but at that point, why not use the REQUIRES?
