+ This is pfaltgall v0.2, a CLI PHP script that can generate an html file with
+a gallery from your Pixelfed profile. The gallery loads each image

+you jump right from the start to any point in the timeline. It also preserves
+each post’s text content and any possible image description (alt-text).
+ In order to create the html gallery file, you just need to login to your
+Pixelfed account and get an app token (Settings -> Applications -> Create new
+token), then create a configuration file for pfaltgall like this (don’t write
