# 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.
