+      TeXmacs has been installed! You can also check some dependencies :
+       * Aspell for spell checking
+       * Gnuplot for inline plotting
+       * ...and a lot more!
+
+      Usually, TeXmacs detects the dependencies at runtime, so you can install
+      them at any time.  If you encounter any problems and are upgrading from a
+      previous version of TeXmacs, you can try to remove the ~/.TeXmacs folder.
