+# All the usual suspects contributed to the dicussion that led
+# to this new work and likewise to the ideas and content in the
+# original (which was probably influenced by gtk), among them:

+
+ wx-config returns information about the wxWidgets libraries available
+ on your system. It may be used to retrieve the information you require
+ to build applications using these libraries.
+
+ If alternative builds of wxWidgets exist on the system, you can use the
+ options: --prefix, --host, --toolkit, --unicode, --debug, --static,
+ --version and --universal, to select from them. Use the --list option to
+ show alternatives available which match specified criteria. The unicode,
+ debug, and universal options take an optional yes or no argument, while
+ host and version accept posix extended regex.
+
+ Optional LIB arguments (comma or space separated) may be used to specify
+ the wxWidgets libraries that you wish to use. The magic "std" label may
+ be used to import all libraries that would be used by default if none were
+ specified explicitly. eg. wx-config --libs core,base.

+# -----------------------------------------------------------------------
+
+# 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.

+# this file until a unique match is made or no alternatives remain that
+# may be sensibly guessed at. It will preferentially bind the unspecified
+# options in the order they are listed in wxconfig_schema. Using this
+# partial ordering it should find the first match with the most significant
+# similarity to this file that unambiguously meets the user specification.
+# If such a match exists it will be output to stdout.
+#
+# Be careful if you modify this function. If the pruning logic is rendered

+# the result. WXDEBUG=findprogress is your friend here, it will show you
