It now recommends PCbuild/get_externals.bat instead of the scripts in
Tools/buildbot.

 The last category of sub-projects listed above wrap external projects\r
 Python doesn't control, and as such a little more work is required in\r
 order to download the relevant source files for each project before they\r
-can be built.  The buildbots must ensure that all libraries are present\r
-before building, so the easiest approach is to run either external.bat\r
-or external-amd64.bat (depending on platform) in the ..\Tools\buildbot\r
-directory from ..\, i.e.:\r
-\r
-    C:\python\cpython\PCbuild>cd ..\r
-    C:\python\cpython>Tools\buildbot\external.bat\r
-\r
-This extracts all the external sub-projects from\r
-    http://svn.python.org/projects/external\r
-via Subversion (so you'll need an svn.exe on your PATH) and places them\r
-in ..\externals (relative to this directory).\r
-\r
-It is also possible to download sources from each project's homepage,\r
-though you may have to change the names of some folders in order to make\r
-things work.  For instance, if you were to download a version 5.0.7 of\r
-XZ Utils, you would need to extract the archive into ..\externals\xz-5.0.5\r
-anyway, since that is where the solution is set to look for xz.  The\r
-same is true for all other external projects.\r
-\r
-The external(-amd64).bat scripts will also build a debug build of\r
-Tcl/Tk, but there aren't any equivalent batch files for building release\r
-versions of Tcl/Tk currently available.  If you need to build a release\r
-version of Tcl/Tk, just take a look at the relevant external(-amd64).bat\r
-file and find the two nmake lines, then call each one without the\r
-'DEBUG=1' parameter, i.e.:\r
-\r
-The external-amd64.bat file contains this for tcl:\r
