+/* This file creates the getbuildinfo.o object, by first
+   invoking subwcrev.exe (if found), and then invoking cl.exe.
+   As a side effect, it might generate PCBuild\getbuildinfo2.c
+   also. If this isn't a subversion checkout, or subwcrev isn't
+   found, it compiles ..\\Modules\\getbuildinfo.c instead.
+
+   Currently, subwcrev.exe is found from the registry entries
+   of TortoiseSVN.
+
+   No attempt is made to place getbuildinfo.o into the proper
+   binary directory. This isn't necessary, as this tool is
+   invoked as a pre-link step for pythoncore, so that overwrites
+   any previous getbuildinfo.o.
