# In XWiki 17 the top bar's logo is the colour theme's. This makes a colour theme of our own,
# FlamingoThemes.StarshipOS -- a copy of the stock Iceberg with our wordmark as its logo -- and
# makes it the wiki's; the stock theme is not touched (set colorTheme back to
# FlamingoThemes.Iceberg to undo). It also makes the browser tab's title "<page> - StarshipOS".
# Run again after changing the wordmark: the logo is replaced. XWIKI_USER and XWIKI_PASSWORD as for
# site/*/install.sh. Everything goes as XML: XWiki refuses form and plain-text writes without its
# form token.
