+# From here on, we'll need to be able to figure out a delegation target.
+# -----------------------------------------------------------------------
+
+# The rules for delegation are:
+#
+# 1. If the specification is so general that it matches the default config
+# (ie. this one on a first pass), then the default config will be used
+# even if other installed libs would also match the spec.
+#
+# 2. If the default config does not match, find a list of all installed
+# libraries that do match.
+# a. If that list is empty, the specification is incompatible
+# with any installed lib. Warn and abort.
+# b. If that list contains exactly one candidate. Delegate to
+# that candidate.
+# c. If the list contains multiple candidates, pass on to step 3.
+#
+# 3. Attempt to discriminate among rival candidates by their similarity
+# to the default configuration (ie. this one). If we can find a unique
+# candidate in this way, delegate to it. If not, present a list of
+# options to the user and request that they disambiguate it with one or
+# more additional fields.
+#
+# To refine the specified pattern, we specialise each unbound field
+# using the default value from this config file. If that results in
+# no matches, we unbind it again and try the next field. If it still
+# results in multiple matches we try binding the next field as well
+# until a unique or null result again occurs.
+#
+# A more general way to look at this, is the feature specifiers are all
+# modifiers of the wx-config you are calling. If you supply none, the
+# default for that build configuration will be used. If you supply one
+# or more that the default build cannot satisfy, it will try to find the
+# config most like itself with the desired feature(s) enabled.
+# The features configured into the first wx-config called will be taken
+# as implicitly specified if it is necessary to disambiguate likely
+# candidates from the information that was explicitly provided.
+
+
+# But first, more sugar to keep what follows clear and legible.

+# partial ordering it should find the first match with the most significant
+# similarity to this file that unambiguously meets the user specification.
