Yes, that's right. I also considered parsing DESCRIPTION. I adjust the function as soon as I find some time. But I won't be sorry, when someone is quicker. :-)

The problem with most add-ins is, that you have no library() etc. call for them in any source files. Those they are hard to spot.

As a workaround: add for each add-in a `library(add-in-package)` in a *.R file.
