+#              Essentially a fresh start this time around, but for maximum
+#              compatibility basic code was taken from, and heavy reference
+#              made to, the previously unattributed wx-config from cvs.
+#              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 required to build
+  applications using these libraries using --cppflags, --cxxflags, --cflags,
+  and --libs options.
+
+    If multiple builds of wxWidgets  are available,  you can use the options
+  --prefix, --host, --toolkit, --unicode, --debug, --static, --universal and
+  --version to select from them. The --selected-config option shows the name
+  of the current configuration and --list shows available alternatives which
+  match specified criteria. The --utility option returns the correct version
+  of UTIL to use with the selected build. The --linkdeps option returns only
+  static libraries for your makefile link rule dependencies.
+
+    The LIBS arguments (comma or space separated) may be used to specify the
+  wxWidgets libraries that  you wish to use. The "std" label may be used  to
+  import all libraries that would be used by default if none were  specified
+  explicitly, e.g. wx-config --libs core,base. The "all" label may  be  used
+  to  import  all libraries that have been compiled which are shown  in  the
+  list  below.  The  --optional-libs parameter should be followed by  a list
+  of  libs that should be linked to, but only if they are available.
+
+  Available libraries in this build are : @BUILT_WX_LIBS@

+#       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.

+# Please.  Avoid addding things here, wx-config should avoid
+# hard coding tool specific details.  Do not use things here
+# as an example of other things that should be here,  These
+# shouldn't be here either.  This is a place of last resort
+# for interim workarounds.  I can but stress as strongly as
+# the censor will allow, there are only bad examples of things
+# that belong at this level of abstraction to follow.  It is
+# a limbo for glitches awaiting the Next Design Repair.  Ok.

+# With that firmly in mind, our debut dilemma is:
+
+# Resource compilers.  An elusive term that covers some pretty
+# dissimilar concepts on various platforms.  The good news is,
+# each platform has only one definition of 'resource', compiled
+# or not, and so we can abstract that neatly to return a platform
+# specific invocation of the appropriate tool.  The bad news is,
+# windres (at least) requires knowledge of the wx header files
+# location(s) that cannot be predicted reliably before the call to
+# wx-config is made.  Currently for all known resource compilers,
+# we can simply return a command and some salient configuration
+# options in response to a request for --rescomp.  So here we
+# top up the options for any tools that may require information
+# that was only just determined in the last few machine cycles,
+# then output the necessary incantation for the platform.
+#
+# Most things should already be constant by the time configure
+# has run.  Do not add anything here that is already known there.
