Version 0.22.1

lxroot now exports FAKEROOTDONTTRYCHOWN=1. (This allows fakeroot and apt-get.)
With -x, added various X display sanity checks and error messages.
With -x, lxroot will test the X display connection by running 'xset -q'.
In a terminal with -x, lxroot will prompt to copy in ~/.Xauthority.
In a terminal with -n, lxroot will prompt to copy in /etc/resolv.conf.
In aux/unit.sh, added interactive tests of above prompts.
In str.cpp, wrote new Str class. (Removed old Str and Frag classes.)
In str.cpp, rewrote string concatenation.
In Makefile, removed demo3. (vland obsoletes demo3.)

Version 0.22.0

vland uses Lxroot's cd path option with relative paths.
Version 0.22.0 of Lxroot improves Lxroot's cd path feature, in order to support vland.

Version 0.21.0

Version 0.21.0 is the initial release of Lxroot! Released 20211226.
I believe issues #6 and #8 are fixed in this release.
(However, I may not close those issues just yet.)
Mostly, I created this release so that a release would exist on GitHub.
I hope to add an x86 statically-linked binary executable version of Lxroot to this release in the near future. (Update: done!)
Given that Lxroot is a new program, you should definitely test Lxroot before using it in production.
I've been using Lxroot in-house for over a year without any problems.
