Modify the templates
--------------------
In most cases, you just need to edit tex/support/header.tex and add your logo
in tex/support . After you changed it, you might want to run
$ python schilder.py --recreate-cache
to delete all cached pdf and image thumbnails, then re-run pdflatex on all
saved signs. Accessing the webinterface will recreate the rest of the cached
image thumbnails.
