Not to rain on your parade with nicely formatted code like hardly any shell projects do, but what I would have expected for such a tool that I just want to use:

wget https://github/.../releases/.../stable/htrace.sh

Only gave it a quick look and saw the other comment asking for dependencies. if there are some, why not list them in the README.

I'm really not against installers, but falls under the "small handy tool" category and not "I will spend time automating the install, either it works or it doesn't"
