+    (description
+     "Package TIPA uses the T3 encoding for producing IPA characters.  The package
+is widely used in the field of linguistics, but because of the old encoding,
+the output documents are less productive than Unicode-based documents.  This
+package redefines most of the TIPA-commands for outputting Unicode characters.
+Users can now use their beloved TIPA shortcuts with the benefits of Unicode,
+i.e., searchability, copy-pasting, changing the font and many more.
+
+As this package needs the @code{fontspec} package for loading an IPA font, it
+needs to be compiled with XeLaTeX or LuaLaTeX.  This package can also be
+viewed as an ASCII-based input method for producing IPA characters in Unicode.
+It needs the New Computer Modern font for printing IPA characters.")
