From the release branch (usually master) generate new PDF and HTML docs, and
copy the doc/install/ directory to $HOME.

Checkout gh-pages and run this script:

rm -r doc html
mkdir doc
cp ~/install/cylc-user-guide.pdf doc/
cp ~/install/suite-design-guide.pdf doc/
for f in ~/install/html/{single,multi}/*.{html,css}; do
    F=${f#*install/}
    mkdir -p $(dirname $F)
    echo cp $f $F
done

Finally:

git checkout -- doc/cylc-autosub-response.pdf

git add any new files under html/
