Publishing a knowledge base with org-mode
This personal wiki is written in org-mode style plain text and exported to HTML.
Oh man. Just discovered org-download. So useful!
Works best with 'import %s' to my mind. gnome-screenshot blocks the window, whereas with import I can still tab around and select which window to capture and all that.
I use this to get a better layout in org-agenda.
Dang, the marking and performing actions of multiple items in the agenda is super useful. Especially to think you can write your own arbitrary function to run, too.
I added this via the pdf layer from spacemacs. It's handy for sure.
