Unman is correct. Additionally, mandb index generation may be of lesser quality because our man pages are not actual man pages, but rather lifted from reStructuredText via pandoc, which generate raw *roff formatting macros rather than semantic mdoc (or even man(7)) ones. This is because reStructuredText inherently lacks such semantics, and pandoc does not attempt to heuristically assign any.
Example: NAME ==== qvm-block - list/set VM PCI devices. Turns into: .TH "qvm\-block" "" "" "" "" .SH NAME .PP qvm\-block \- list/set VM PCI devices. Instead of: .Sh NAME .Nm qvm-block .Nd list/set VM PCI devices -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
