Hi Vikram,
I was wondering what that does as well. As far as I could tell it will call cObjGetSingle with the current instance of tslib_cObj. i.e. you can 
create a custom content object that is then processed just like any other cObj (IMAGE, TEXT, USER etc.) with the current data array (presumably 
the tt_products records in the basket).

You can set it via TS, for example:
plugin.tt_products.externalProcessing = TEXT
plugin.tt_products.externalProcessing.value = hello world

This would be output in the shopping basket where the appropriate marker is set. The example doesn't make much sense, rather I expect you'd be 
using a cObject 'USER'.
There are two other cObjects that you can define. 'externalFinalizing' and 'externalProcessing_final'. To process your record array *after* the 
order has been sent you could do:

includeLibs.externalFinalizing = my/own/script.php
plugin.tt_products.externalFinalizing = USER
plugin.tt_products.externalFinalizing.userFunc = user_externalFinalizing -> myMethod

I never tried it but that's my best guess. I'd be interested to hear how it works if you decide to try it out...
Cheers,
Simon
