libghc-raw-strings-qq-dev binary package in Ubuntu Focal riscv64

 A quasiquoter for raw string literals - that is, string literals that don't
 recognise the standard escape sequences (such as '\n\). Basically, they
 make your code more readable by freeing you from the responsibility to
 escape backslashes. They are useful when working with regular expressions,
 DOS/Windows paths and markup languages (such as XML).
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
