Background: failed to build linux kernel documentation (still too lazy to solve
Goal: generate pdf files of linux documentation, because I have reading problem when using text files. Text files look ugly when I open using my reader (Android).
Install needed packages.
Do this simple tricks.
Now I have pdf files of all the text files.
It still have a problem, it just convert files on the same directory. So other files under this directory must be processed separately, which mean I must move to each directory.
