 # 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, perfer 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.

What's that?

[Dirk Pranke, 2016/02/09 19:38:03]

I also am assuming this is a weird/bad merge and needs to go away.

[Zachary Forman, 2016/02/09 20:57:35]

Correct! Will remove.
