- ensure we use docstrings in a Sphinx-compatible manner?
https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html
at the very least document all the functions and such so pydoc's happy.
- better prompt display. i might include them as constants in a separate file
and then import it for e.g. confgen. or maybe a Flask website/app?

- locking
- for docs, 3.x (as of 3.10) was 2.4M.
- GUI? at least for generating config...
- Need ability to write/parse mtree specs (or a similar equivalent) for applying ownerships/permissions to overlay files
- xNeed ability to write/parse mtree specs (or a similar equivalent) for applying ownerships/permissions to overlay files
-- parsing is done. writing may? come later.

- SSL key gen:
import OpenSSL
k = OpenSSL.crypto.PKey()
k.generate_key(OpenSSL.crypto.TYPE_RSA, 4096)
x = OpenSSL.crypto.dump_privatekey(OpenSSL.crypto.FILETYPE_PEM,
k,

This directory contains example files/data that you may see referenced in documentation/code.

- mtree.spec
This file is an example mtree spec sheet that one may use for an overlay. It was generated by the command "mtree -c -K all -p /home/bts".
If you're on Arch, a port of mtree can be found in the AUR under the package name "nmtree" (it's maintained by the same author as BDisk!).
If you're on Debian or Ubuntu (or forks thereof), you can find it in the "freebsd-buildutils" package. (The executable is called "fmtree").
If you're on Gentoo, it's in sys-apps/mtree.
If you're on RHEL/CentOS, the "extras" repository has gomtree, which (although written in Go) should be able to produce mtree spec files (but this is unknown for certain).
