A tool to filter packages from the definition files
===================================================
An example of the usage for a useful report of what is specified in the config
but not available in the compose:

./get_pkgs_sst.py --filter-sst=sst_cs_apps configs/*.yaml 2>/dev/null >/tmp/sst
for r in BaseOS AppStream ; do
  dnf repoquery --refresh --available --repofrompath="a,https://odcs.stream.centos.org/test/latest-CentOS-Stream/compose/$r/x86_64/os/" \
                --disablerepo=\* --enablerepo=a --qf '%{name}'
done | sort -u >/tmp/supported

for r in BaseOS AppStream CRB ; do
  dnf repoquery --refresh --available --repofrompath="a,https://odcs.stream.centos.org/test/latest-CentOS-Stream/compose/$r/x86_64/os/" \
                --disablerepo=\* --enablerepo=a --qf '%{name}'
done | sort -u >/tmp/shipped

cat /tmp/sst | while read -r c ; do
  if ! grep -q -e "^$c$" /tmp/supported ; then
    if ! grep -q -e "^$c$" /tmp/shipped ; then
      echo "$c not shipped at all"
    else
      echo "$c not fully supported (CRB only)"
