"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. # 'variables': { # level 1 'variables': { # level 2 # Variables needed by conditions list within the level-2 variables dict.
