`lnav` is a fab tool for analysing logs. Today I used it for debugging a verbose `strace -f` log file to analyse what the problem was w/smth and it was cool

Tip: hit `<tab>` to edit, enable, and disable existing text filters added w/e.g. `:filter-in` and `:filter-out`.

Is there anything better than strace these days for debugging why stuff is crashing these days? Esp. when it is deeply nested aka a child process of a child process of a child process?

Edit: And when a translation layer like wine is involved.
