I understand that the following question has been answered
but my question differs from it. I just installed MacTeX and it used over 4 gigabytes of space on my computer. I understand the full LaTeX uses many, many libraries, but this is as big or bigger than an operating system. So my question is:
Why can't the developers of TeX Live create it so it has very low overhead?
Details would be really appreciated.
I can only imagine the possibilities such as including it in web browsers and other applications/plugins (keynote, powerpoint, etc.).
