Absolutely yes! Exists in the wild in many flavors, but Eclipse is a great example. There is so much joy for both you (writing documentation) and your users when the complete installation instructions are:
- Unzip/decompress the download
- Open up the resulting folder and run "awesomeprogram"
And the complete uninstall instructions are:
- Delete folder
Feel free to copy that text, I won't charge you for it :)
This approach also is one with all that is right and natural in the universe because it is very normal for computer users to apply the following concept (it works for every spreadsheet/.doc/.pdf/.jpg/.mp3 they've ever worked on):
"If I want something, I copy it from someplace and put it on my computer. If I want to get rid of something, I delete it"
You might want to do an "export settings" for people who want to uninstall/reinstall (who the heck does that on a regular basis for a single user anyway?) if you have preference files. But then again, if someone is uninstalling, they probably don't give a rip about ever using the software again, no? :)
