  This is {$SCRIPTNAME} v{$SCRIPTVERSION}, a CLI PHP script that can generate an html file
 with a gallery from your Pixelfed profile. The html gallery file will load

-space and let you jump right from the start to any point in the timeline.
-It will also show each post’s text content, its date, and provide each image
-with its description (alt-text), if present.
