That's at odds with what I've read online which admittedly may be all
junk.  I wanted to try Flask so I installed the Ubuntu packages but then
got stuck on a huge document that suggested I needed to install things
called Nginx and Gunicorn.  You've now mentioned another: Heroku.  I'm
sure the complex instructions I found are not really required -- it was
probably just the usual "this is what I did so this is how it's done"
document, but I'm having trouble finding the simpler way to do it.

Since no web server configuration is needed (I have a working Apache
installation that mirrors, as closely as possible, what my hosting
provider uses) it should be relatively easy.  Can you tell me, or can
you point me to a resource that tells me, where to put the app?  I don't
yet know what "push your code to Heroku" means.
