# Start Vim on a copy of the tutor file.
# 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 :-).
