  # 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 ,
  # which deals with these same constraints in a similar manner.
