Subject: Update, once and for good, the copyright year
X-Git-Tag: pool-3.1~29
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea76ab81ba1d797eee2baf2a1464be51e608b8bd;p=thirdparty%2Fpsycopg.git

Update, once and for good, the copyright year

After getting more information about the matter and having convinced
myself that there is no need, except FOMO, to extend the copyright year
on source code, change all our entries to leave only the start year.

    git ls-tree -r HEAD --name-only \
        | xargs sed -i '/Copyright.*\(Varrazzo\|Psycopg\)/ s/-20..//'
