This seems like a simple question, but I am looking for an in-depth answer.
I did a manual installation on OSX by downloading the sage tar file and running make. I now have a sage-7.2 folder which seems to contain all of sage.
For example, sage doesn't seem to use any python libraries on my computer, but instead installs all python libraries locally in sage-7.2/local/lib/python2.7.
Are there any large libraries/files that sage installs that are NOT in the sage-7.2 folder? About how much space do these external files take up?
