+italics and small capitals.  According to its designer, Pablo
+Impallari, Cabin was inspired by the typefaces of Edward Johnston and
+Eric Gill.  Cabin incorporates modern proportions, optical adjustments
+and some elements of the geometric sans.  @code{cabin.sty} supports
+use of the font under LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX.  It uses
+the @code{mweights} package to manage the user's view of all those
+font weights.  An @code{sfdefault} option is provided to enable Cabin
+as the default text font.  The @code{fontaxes} package is required for
+use with [pdf]LaTeX.")
