Similar to this question, I would like to figure out which packages I am using, with a twist - I'd like to know which of these are not included in the generic Miktex distribution, so I can download them and add them to a local configuration-managed repository.
Is there an easy way to do this?
Edit: as a point of clarification, with the auto-install option enabled, packages are downloaded from CTAN in addition to what normally is included when miktex is installed. Additionally, some packages have updates downloaded. My question is how to put the whole thing under CM control such that I can be assured that this particular configuration will work for my document templates. I'd like to be able to create my own on-disk package repo from this to run in a closed environment (no internet access).
