##
# A TargetConfig is a wrapper around an RbConfig object that provides a
# consistent interface for querying configuration for *deployment target
# platform*, where the gem being installed is intended to run on.
#
# The TargetConfig is typically created from the RbConfig of the running Ruby
# process, but can also be created from an RbConfig file on disk for cross-
# compiling gems.
