Came across a site http://rawgit.com/ that https isn't required therefore people without OpenSSL can read it. This means you auto update your script from Github, and it should work for everyone. 
Just copy the URL from your browser while browsing the file you want to read, and use that as the URL parameter.
Example:
Simba Code:
Writeln(GetGithubPage('https://github.com/SRL/SRL-6/blob/master/lib/utilities/drawing.simba'));
And the function (ps & Lape):
Simba Code:
function GetGithubPage(const URL: String): String;
var
NewURL: String;
p: Integer;
begin
Result := '';
p := Pos('.com/', URL);
if (p = 0) then
Exit;
NewURL := Copy(URL, p + Length('.com/'), Length(URL) - p + Length('.com/'));
Result := GetPage('http://cdn.rawgit.com/' + Replace(NewURL, 'blob/', '', [rfReplaceAll]));
end;
