This script enable you to open a url which is first one in the line in your default browser.
You need a python interface.
If there is a line such that
You use ':OpenUrl' command in this line, then you can open http://aaa in a default web browser.
I set a command for OpenUrl function, such that
command OpenUrl :call OpenUrl()
You can change command name by changing above command name 'OpenUrl'.
command AnotherOpenUrlName :call OpenUrl()
