# Builds the web UI's logo from the master, artwork/logo.svg (a key whose
|
|
# bow is a crown with Jarl's network nodes, in Jarl's blue and white):
|
|
#
|
|
# internal/web/static/assets/logo.svg the favicon (a copy)
|
|
# internal/web/static/assets/logo.js the shapes for the web UI, which
|
|
# draws them inline (brand.js), so the
|
|
# logo appears together with the page
|
|
#
|
|
# The master is hand-written SVG: <g> elements whose attributes apply to
|
|
# their <path> and <circle> children. It then runs scripts/banner.py to
|
|
# rebuild the README's banner. Run from the repository root after changing
|
|
# it:
|
|
#
|
|
# python3 scripts/logo.py
