> Given there are existing realpath utils in both BSD and Debian, It is not necessarily everybody knows realpath. By default ubuntu doesn't have realpath installed. I'm not sure we should make the name less obvious than it should be just because there is a different that happen share some commonalities. Figuring out there is a option --relative in realpath is always going to be harder than figure out there is a command named relpath. When we name a function, we should emphasize more how users are going to find it.
I'll let other people comment on the choice of the name for the users' perspective. -- Regards, Peng
