Some changes we've made to our Evergreen OPAC
Most of these go in /openils/var/templates/opac, but the icon_formats directory should go in /openils/var/web/images/format_icons
The following commands -- run as opensrf -- should get all our customizations into an existing Evergreen installation:
cd /openils/var/templates/opac
git init
echo "*" >> .gitignore
git remote add origin https://github.com/lbcclib/tpac_customizations
git pull origin master
git reset --hard origin/master
cp -R icon_format/* /openils/var/web/images/format_icons/icon_format/
