Subject: Move welcome text into a separate file.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=8a8c680db7b6fb0d73da43c1da0beb8aee7da1e6;p=edlib.git

Move welcome text into a separate file.

This makes it easier to edit the welcome text, and to have different
welcome text for different editors.
