Inlining the LaTeX \input Command

Question

I'm looking a program to recursively inline all \input{} commands in a LaTeX file. By "recursively", I mean doing the inlining iteratively until no \input{} command remains in the final LaTeX file.

I've already come across the flatten package. But, for some reason, my TeXLive distribution doesn't install it. When I execute the command sudo tlmgr show flatten, I get the error message: tlmgr: cannot find flatten. So, I'm looking for alternative tools that are more standard and easier to install.

Answer 1

Why don't you just download flatten from CTAN (the link you gave in the question) and install it manually?

EDIT: Apply the following patch to fix the build errors.
