+// mini_installer.exe is the first exe that is run when chrome is being
+// installed or upgraded. It is designed to be extremely small (~5KB with no
+// extra resources linked) and it has two main jobs:
+//   1) unpack the resources (possibly decompressing some)
+//   2) run the real installer (setup.exe) with appropiate flags.
+//
+// In order to be really small we don't link against the CRT and we define the
+// following compiler/linker flags:
+//   EnableIntrinsicFunctions="true" compiler: /Oi
+//   BasicRuntimeChecks="0"
+//   BufferSecurityCheck="false" compiler: /GS-
+//   EntryPointSymbol="MainEntryPoint" linker: /ENTRY
+//   IgnoreAllDefaultLibraries="true" linker: /NODEFAULTLIB
+//   OptimizeForWindows98="1"  liker: /OPT:NOWIN98
+//   linker: /SAFESEH:NO
+// Also some built-in code that the compiler relies on is not defined so we
+// are forced to manually link against it. It comes in the form of two
+// object files that exist in $(VCInstallDir)\crt\src which are memset.obj and
+// P4_memset.obj. These two object files rely on the existence of a static
+// variable named __sse2_available which indicates the presence of intel sse2
+// extensions. We define it to false which causes a slower but safe code for
+// memcpy and memset intrinsics.
+
+// having the linker merge the sections is saving us ~500 bytes.
