Making PowerShellGallery modules Portable

I'm a big fan of PowerShellGallery. It's easy to use, Microsoft owned, a place to host your PowerShell modules. Every time I release a new PowerShell module, it's readily available for me or anyone with a single command Install-Module. No need to host it yourself, no need to prepare anything - plug & play. Additionally, if your PowerShell module has any dependencies, it will download and install them, so it directly works out of the box. But what if you can't use PowerShellGallery? What if you don't want to use Install-Module on 100 computers, but you prefer to do it in a more controlled way? What if your servers do not have internet connectivity?

Sixteen PowerShell modules that I’ve worked on in 2018

We're a few days in 2019, and from a time perspective, I can say I had a busy 2018. I must say I've never expected that but in 2018 I've created or worked on 24 PowerShell modules. Some were simpler ones, some were a bit more advanced, and some will be retired in 2019 because their features will be moved to other modules. In PowerShellGallery alone those were downloaded over 15000 times (I must admit that some of those are surely automated tests - "Hello Pester" that I've learned in 2018. It's a nice number thou, and something I'm kind of proud of myself. After all, before 2018 I've not created a single PowerShell module before. Sure, I've created a bunch of scripts, hardcoded, that did the task that I had to solve. But I've never before built something, that could be installed by one little command Install-Module (something I've learned in 2018 as well) and executed by anyone, anywhere. I know the title says Sixteen PowerShell Modules but some modules are just too simple to give them anything else than a small mention.

A command with name is already available on this system. This module may override the existing commands.

Another day, another issue one may say. Today I wanted to install one of my modules to a new server and was greeted with a well-known message (it may seem on first look): A command with name '' is already available on this system. This module 'PSEventViewer' may override the existing commands. If you still want to install this module 'PSEventViewer', use -AllowClobber parameter.
