Semi automated conversion, in part because Pandoc is kind of buggy for adoc:

Some of the commands were along the lines:

    for f in *.md; do pandoc --atx-headers --base-header-level=3 -o ${f%.md}.adoc --wrap=none $f; done
    sed -Ei '/\[\[.*\]\]/d' *.adoc
    while read -r f; do cat $f; echo; done <f >g

= user

Userland C programs used to test our kernel modules.

`sh` programs are simpler, and installed by copying directly with an overlay.

C programs require cross compiling, but give us more control over system calls.

These programs can also be compiled and used on host.
