indeed: for a niche/developer-only use, the bar of tool requirements can
be higher IMO. Besides, /usr/gnu/bin/grep is there, too (or could be;
both /usr/xpg4/bin/grep and /usr/gnu/bin/grep live in separate packages
that may or may not be installed).
I just want to make the entry barries for normal builds as low as
