libdirectory-scratch-perl binary package in Ubuntu Oracular riscv64

 When writing test suites for modules that operate on files,
 it's often inconvenient to correctly create a platform-independent
 temporary storage space, manipulate files inside it, then clean it
 up when the test exits. The inconvenience usually results in tests
 that don't work everywhere, or worse, no tests at all.
 .
 Directory::Scratch aims to eliminate that problem by making it easy to
 do things right.
