2 Use of Packages

Additional commands/structures defined in packages.

For example, latexsym defines special math symbols, such as \Box [].

To use it:


  \documentclass{article}
  \usepackage{latexsym} % Loads latexsym.sty
  \begin{document}
  . . .
  \end{document}

Note: \usepackage can only be used in the preamble; i.e., it must come before the \begin{document} line.
