 % \section{Introduction}
 % With \LaTeX, the user has to decide manually to not number an equation by adding a star in the math environment. Authors who do not want to think about the numbering during the writing (and maybe they should not), often use the environments without stars. As default, these users get all equations numbered, although there are \href{http://tex.stackexchange.com/q/29267/7323}{different opinions} about what should be numbered.

 % This is a simple helper macro to mark a label as referenced. The reference information is stored into a variable (for the current run) and into the aux file (for the next run), so it does not matter if the reference is used before or after the definition of the label. Saving into a variable saves one compilation run, although still up to three are needed to get everything right.
