Subject: doc: make legacy digest utility --help reference cksum nodes
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7426643f393dc27d08a61ff398d89ffe092c0c56;p=thirdparty%2Fcoreutils.git

doc: make legacy digest utility --help reference cksum nodes

* src/system.h (oputs_): Map md5sum etc. to cksum urls,
as we only have cksum anchors in the manual to avoid
creating anchors for all of the legacy digest utilities.
