# README
# this package requires glibc-debug to run the check() function
# as -debug packages are not available in [core], it has to be applied manually
# whenever the tests shall run
#
# For a fresh build:
# $repo-x86_64-build -- -I ../../glibc/trunk/glibc-debug*.pkg.tar.zst
# $repo-x86_64-build
# ${repo}pkg
