Run make/mirror.py to download resources we mirror from elsewhere into
the "mirror" directory.

Run make/splitols.py to break up the OLS proceedings into individual
papers.  (Run mirror.py and install pdftk first.)

Run make/make.sh to rebuild documentation extracted from the kernel
source tarball.  You may want to set $WEBDIR and $LNXDIR to values appropriate
for your system, and install mercurial and xmlto first.  This calls most
of the other scripts in this directory.

Run make/doclinkcheck.py to check the Documentation/index.html files for
404 errors or files not mentioned from the index.  (These are generated
from 00-INDEX files in each subdirectory, so the errors it reports should
be fixed upstream in the Linux kernel source.)
