The new [ParseCookie] function parses a Cookie header value and
returns all the cookies which were set in it. Since the same cookie
name can appear multiple times the returned Values can contain
more than one value for a given key.

The command prefix [cond] indicates that the command on the rest of the line
should only run when the condition is satisfied.

A condition can be negated: [!root] means to run the rest of the line only if
the user is not root. Multiple conditions may be given for a single command,
for example, '[linux] [amd64] skip'. The command will run if all conditions are
satisfied.

When TestScript runs a script and the script fails, by default TestScript shows
