\section*{Introduction}
A poster class for \LaTeX that attempts to follow the UCL Corporate Identity.
This package is unofficial and is not supported by UCL.
Currently only compilation with XeLaTeX is supported.
\section*{Installation and usage}
Copy the `uclposter.sty` file to the directory containing the poster LaTeX file.
No additional files are needed (the banner/logo is included entirely as vector drawing code).
\section*{Highlight boxes}
\begin{highlightbox}
The \textbackslash highlightbox command inserts a coloured box, the default colour is a lighter version of the banner colour.
\end{highlightbox}
\begin{highlightbox}[UCLdarkblue!20!white]
The colour of a \textbackslash highlightbox can also be changed.
\end{highlightbox}
