+# Usage: vimtutor [-g] [xx]
+# Where optional argument -g starts vimtutor in gvim (GUI) instead of vim.
+# and xx is a language code like "es" or "nl".
+# When an argument is given, it tries loading that tutor.
+# When this fails or no argument was given, it tries using 'v:lang'
+# When that also fails, it uses the English version.
+
+# Vim could be called "vim" or "vi".  Also check for "vimN", for people who
+# have Vim installed with its version number.
+# We anticipate up to a future Vim 8 version :-).
