# This PortGroup lets a port check that the user's Xcode is sufficiently new.

#

# Usage:

#

#   PortGroup               xcodeversion 1.0

#   minimum_xcodeversions   {darwin_major minimum_xcodeversion}

#

# where darwin_major is the major version of the underlying Darwin OS (e.g. 16

# for macOS 10.12 Sierra) and minimum_xcodeversion is the minimum version

# of Xcode the port requires (e.g. 3.1).
