+% The package provides two commands for placing an arc over or under
+% a short (up to three letters) piece of text. The commands generate an
+% |\hbox| and can be used in math formulas
+% (see \textit{The \TeX{}book}, p.\,151).
+%
+% |\overarc| puts an arc above the text given as argument.\\
+% |\underarc| puts the arc below the text.
+%
+% The size of the arc is chosen so that it embraces all the text. In
+% some cases, you may wish to use a smaller or larger size. An
+% optional argument can specify a factor which
+% is multiplied by the width of the text: the size of the symbol is then
+% chosen as if the text had that width. Keep in mind, however, that only
+% a limited range of sizes is available in the Computer Modern fonts.
