eng/build.ps1

#
# This script controls the Roslyn build process. This encompasess everything from build, testing to
# publishing of NuGet packages. The intent is to structure it to allow for a simple flow of logic
# between the following phases:
#
#   - restore
#   - build
#   - sign
#   - pack
#   - test
#   - publish
#
# Each of these phases has a separate command which can be executed independently. For instance
# it's fine to call `build.ps1 -build -testDesktop` followed by repeated calls to
# `.\build.ps1 -testDesktop`.
