If you want to customise the 'top' of the page, if you just create the file 'name-of-protocol.top' e.g. wellpet.top, this will be used automatically. Likewise 'name-of-protocol.bot' e.g. wellpet.bot, will be added at the end of the page.
The XXX.top file will be inserted after the 'body' tag. The default for top is the Protocol title, while the default if the XXX.bot file is missing is 'Prepared by date'.
