Reminds me of PowerShell. There's extensive, detailed and super-useful documentation for pretty much all the commandlets available... but it's not installed by default. Get-Help ... will happily tell you that you need to download help if you want to see any details beyond command signature. Who in their right mind though this is a good idea? Such documentation should be shipped with the default install.

I have it on the top of my mind because it bit me twice in recent month. I had to do some PS work on some VMs that didn't have Internet access (beyond RDP). Sure, I can Alt+Tab to a browser on my machine, but at this point, why even have Get-Help? Contrast that with Emacs experience, where everything is documented, and documentation is easily accessible, off-line, and by default.
