-## What
-
-This is intended to be a temporary measure until either the toolchain is
-improved or the code can be physically separated into two DLLs (based on a
-browser/child split).
-
-The link replacement forcibly splits chrome.dll into two halves based on a
-description in `build\split_link_partition.py`. Code is primarily split along
-browser/renderer lines. Roughly, Blink and its direct dependencies are in the
-"chrome1.dll", and the rest of the browser code remains in "chrome.dll".

-TODO: build\split_link_partition.py doesn't exist.

-Splitting the code this way allows keeping maximum optimization on the Blink
-portion of the code, which is important for performance.
