+The authors of the CTAN team listed ten good reasons
+for using \TeX. Among them are:
+\begin{quotation}
+    \TeX\ has the best output. What you end with,
+    the symbols on the page, is as useable, and beautiful,
+    as a non-professional can produce.
+
+    \TeX\ knows typesetting. As those plain text samples
+    show, \TeX's has more sophisticated typographical algorithms
+    such as those for making paragraphs and for hyphenating.
+
+    \TeX\ is fast. On today's machines \TeX\ is very fast.
+    It is easy on memory and disk space, too. 
+
+    \TeX\ is stable. It is in wide use, with a long history.
+    It has been tested by millions of users, on demanding input.
+    It will never eat your document. Never.
