Ballad of asdf
Once upon a time there was a programming language There were many versions of it So people wrote a version manager for it To switch between versions for projects Different, old, new.
Then there came more programming languages So there came more version managers And many commands for them
I installed a lot of them I learnt a lot of commands
Then I said, just one more version manager Which I will write instead
A version manager so extendable for which anyone can create a plugin To support their favourite language No more installing more version managers Or learning more commands
This was the mail I wrote to a few friends to tell them about the project. Thanks to @roshanvid for suggesting that this go into the readme
