Subject: dev-manual, ref-manual: Cross-references between PR Service and cache
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a005cdaaedaadfeff8147bcb5050346314fd8bcb;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

dev-manual, ref-manual: Cross-references between PR Service and cache

Fixes YOCTO #3684

These changes help tie in the relationship between how the OE
build system uses checksums and such and the PR Service that
can track revision.
