[jQuery] Possible jQuery versions conflict

[jQuery] Possible jQuery versions conflict


Greetings,
The task: to insert a DOM-style JS code using jQuery into a thrid-
party page. Example: code snippets used to generate AdSense blocks.
This will require a user to include a jQuery source (directly or
indirectly - either the user includes it, or my code snippet does).
The problem: if the page already uses jQuery, the problem looks
inevitable when two jQuery libraries, most probably of different
versions, are loaded.
What is the simplest way to load jQuery in such a case without causing
JS errors?
Thank you.
