 6/* This file creates the getbuildinfo.o object, by first
 7   invoking subwcrev.exe (if found), and then invoking cl.exe.
 8   As a side effect, it might generate PC\VS7.1\getbuildinfo2.c
 9   also. If this isn't a subversion checkout, or subwcrev isn't
10   found, it compiles ..\\..\\Modules\\getbuildinfo.c instead.
11
12   Currently, subwcrev.exe is found from the registry entries
13   of TortoiseSVN.
14
15   No attempt is made to place getbuildinfo.o into the proper
16   binary directory. This isn't necessary, as this tool is
17   invoked as a pre-link step for pythoncore, so that overwrites
18   any previous getbuildinfo.o.
