# LaTeX Packages

## amssymb and bm

bm, if used, must come after amssymb; otherwise `Error: Too many symbol fonts declared` ensues.

## amssymb, mathdesign and stmaryrd

amssymb and stmaryrd break if used together (`\circledS` command defined by both). This particular command is also defined by `mathdesign`. To overcome this, before loading amssymb, do `\let\circledS\undefined`.

## biblatex

Requires `etoolbox` (provides `\patchcmd`). This means that commands that require `etoolbox` can be placed after loading `biblatex`, and they will work, even if `etoolbox` has never been `\usepackage`’d in the current file. However, for readability it is better to just use `\usepackage`.

## mathdesign

``````\usepackage[bitstream-charter]{mathdesign}
\renewcommand\scdefault{sc}``````

The second line ensures that small caps continue to function… (otherwise they break).

## minted

Loads `etoolbox` (which provides `\patchcmd`).

## xcolor

The `documentclass` line contains one option, `dvipsnames*`, that belongs to the `xcolor` package, but setting it only when loading `xcolor` might cause conflicts with other packages that also automagically load that package (namely `tikz`). Having that option given to `documentclass` avoids the possibility of any such conflict. (What this particular option does, incidently, is to load a set colours larger then the basic set, which contains the colour `MidnightBlue`, used for hyperlinks. The starred version loads colour on demand, i.e. requires a `\providecolors` command.)
