# HOW TO WRITE CONDITIONALS IN THIS FILE
# ======================================
#
# In many other places, one would write a conditional that expresses all the
# cases when a source file is used or unused, and then either add or subtract
# it from the sources list in that case
#
# Since base includes so many low-level things that vary widely and
# unpredictably for the various build types, we prefer a slightly different
# style. Instead, there are big per-platform blocks of inclusions and
# exclusions. If a given file has an inclusion or exclusion rule that applies
# for multiple conditions, prefer to duplicate it in both lists. This makes it
# a bit easier to see which files apply in which cases rather than having a
# huge sequence of random-looking conditionals.
