+Description: Packaging helpers for building D code
+ This package contains common code for building D software for
+ the Debian (and derivatives) archive.
+ .
+ It currently contains a debian/rules snippet for selecting the
+ appropriate D build flags based on the default D compiler set
+ for the current architecture.
