Author: Ricardo Wurmus
Maintainer: Guix Schmeeks <guix@gnu.org>
URL: http://gnu.org/s/my-example
Description: This is a long description

there is a colon : on the lines.
  And: this line continues the description.
biocViews: 0
SystemRequirements: Cairo (>= 0)
Depends: A C++11 compiler. Version 4.6.* of g++ (as
	currently in Rtools) is insufficient; versions 4.8.*, 4.9.* or
	later will be fine.
