The `microtype' package provides a LaTeX interface to pdfTeX's micro-typographic extensions: character protrusion and font expansion. It allows to restrict character protrusion and/or font expansion to a certain set of fonts, and to configure micro-typographic aspects of the fonts in a straight-forward and flexible way. Settings for various fonts are provided. Note: Font expansion and character protrusion only works with the pdfTeX compiler, at least version 0.14f, resp. version 1.20a, for automatic font expansion.
