   # Get ready for the ugly...
   #
   # - We have to nest our variables dictionaries multiple levels deep, so that
   #   this and other gyp files can rely on previously-set variable values in
   #   their 'variables': { 'conditions': [] } clauses.
   #
   #   Example 1:
   #   Within this file, we use the value of variable 'skia_os' to set the
   #   value of variable 'os_posix', so 'skia_os' must be defined within a
   #   "more inner" (enclosed) scope than 'os_posix'.
   #
   #   Example 2:
   #   http://src.chromium.org/viewvc/chrome/trunk/src/third_party/libjpeg/libjpeg.gyp?revision=102306 ,
   #   which we currently import into our build, uses the value of 'os_posix'
   #   within the 'conditions' list in its 'variables' dict.
   #   In order for that to work, it needs the value of 'os_posix' to have been
   #   set within a "more inner" (enclosed) scope than its own 'variables' dict.
   #
   # - On the other hand, key/value pairs of a given 'variable' dict are only
   #   inherited by:
   #   1. directly enclosing 'variable' dicts, and
   #   2. "sibling" 'variable' dicts (which, I guess, are combined into a single
   #      'variable' dict during gyp processing)
   #   and NOT inherited by "uncles" (siblings of directly enclosing 'variable'
   #   dicts), so we have to re-define every variable at every enclosure level
   #   within our ridiculous matryoshka doll of 'variable' dicts.  That's why
   #   we have variable definitions like this:  'skia_os%': '<(skia_os)',
   #
   # See http://src.chromium.org/viewvc/chrome/trunk/src/build/common.gypi?revision=127004 ,
