That’s a very good remark!
I definitely cannot reproduce it, so I’m assuming this is what happened:
- I google for something like
opam install binary; - I mis-clicked the second link on the results (
https://opam.ocaml.org/doc/1.2/Install.html, with the extra1.2in the middle), but because both have the same title and overall layout, I didn’t notice the 1.2 in the page; - I copied the wget command for
opam_installer.shand got the weird results. - Because my VM didn’t have Guest Additions, I couldn’t copy the command back to my host, so I re-googled to get it and ask the question, and didn’t notice it was the “right” page this time.
That’s the most reasonable explanation I can provide.
So, other than maybe suggesting that the old documentation pages include a “warning: obsolete” message somewhere, there’s nothing to be done. Sorry for the noise and thanks for the remark!
