Initial Package Version: 2.7.8
Upstream Status: BLFS-specific
Origin: BLFS
Description: For a while we have been using a sed to allow graphviz
to be treated as optional instead of required. With new releases it
becomes hard to determine what changes to make so that the sed will
do the right thing. In this case a patch shows what we want to
achieve, and often (e.g. from 0.40.8 to 0.42.0) applies with only
an offset.
