Is it not possible to create a library exclusively from other
libraries? That is, can multiple .a files are combined to create one .a
file?

I have a code base that is broken up in to three static libraries.
However, I want to distribute/deploy these libraries as one lib file.

[Are libraries still just a concatenation of object files, or are they
more complicated these days?]
