I made a gopher server in python. It's what's running this gopherhole. The
initial version was written in one day: 2017/10/08. At that point, I had
chrooting and privilage dropping sorted out. It could serve static files.
The next day, I implemented guestbook functionality (better not CGI scripts
because I don't want to deal with those). This python script runs this website.
It can be found at gopher://dread.life:70/0/projects/gopher.py in this
directory. Give suggestions at gopher://dread.life/7/guestbook

To run:    sudo python2.7 gopher.py 70

It runs with other pythons to my knowledge.
Change 70 to whichever port you want.
