Alp, Andrey

The old build system printed out every command line; and I often copy-paste that info to build single modules.

Eg currently, when trying to understand #15570 I see a suspicious GHC.Real.hi.  So I want to manually recompile GHC.Real (from base), adding some debug flags.  How can I get the right command line to do that from the build log?

Where is the “how to use Hadrian” wiki page?  I know you’ve been writing one.
