+  Configuration header that defines reasonable defaults at compile time.
+
+  This allows compile-time configuration from the command line, while still
+  allowing the source to be built "as-is" without any configuration.  The idea
+  is to support an advanced build system with configuration checks, while still
+  allowing the code to be simply "thrown at a compiler" with features
+  determined from the compiler or system headers.  Everything can be
+  overridden, so it should never be necessary to edit this file to build
+  successfully.
+
+  To ensure that all configure checks are performed, the build system can
+  define INGEN_NO_DEFAULT_CONFIG to disable defaults.  In this case, it must
+  define all HAVE_FEATURE symbols below to 1 or 0 to enable or disable
+  features.  Any missing definitions will generate a compiler warning.
+
+  To ensure that this header is always included properly, all code that uses
+  configuration variables includes this header and checks their value with #if
+  (not #ifdef).  Variables like USE_FEATURE are internal and should never be
+  defined on the command line.
