#
# To execute this test requires two terminals, one for running Vim and one
# for executing the test script.  Both terminals should have their current
# working directories set to this directory (the one containing this test.py
# script).
#
# In one terminal, launch a GNU ``screen`` session named ``vim``:
#   $ screen -S vim
#
# Within this new session, launch Vim with the absolute bare minimum settings
# to ensure a consistent test environment:
#  $ vim -u NONE
#
# The '-u NONE' disables normal .vimrc and .gvimrc processing (note
# that '-u NONE' implies '-U NONE').
#
# All other settings are configured by the test script.
#
# Now, from another terminal, launch the testsuite:
#    $ ./test.py
#
# The testsuite will use ``screen`` to inject commands into the Vim under test,
# and will compare the resulting output to expected results.
#
# Under windows, COM's SendKeys is used to send keystrokes to the gvim window.
# Note that Gvim must use english keyboard input (choose in windows registry)
# for this to work properly as SendKeys is a piece of chunk. (i.e. it sends
# <F13> when you send a | symbol while using german key mappings)
