Looks like the errors are actually caused by faults in the Rascal tutor docs. Looking into it.

[toinehartman]

For the module lang::box::\syntax::Box, the Tutor generates links with escaped names ([Box](../..//Library/lang/box/\syntax/Box.md#lang-box-\syntax-Box-Box)), but paths without the backslash:

$ ls target/classes/docs/Library/lang/box/
index.md  syntax/  util/

I would expect this to be the cause of the "file not found" errors in the CI here.

As @DavyLandman pointed out elsewhere, it is this one: usethesource/rascal#2910

[toinehartman]

The other error seems to originate from literal HTLM tags in a @description. Should these be escaped in the description itself, or maybe by the Tutor?
