# * libaom tries to detect what version it is
# * I couldn't get it to grab this from git info,
# (which needs at least leaveDotGit=true)
# * it uses a perl script to parse from CHANGELOG,
# but 1.0.0 doesn't contain an entry for itself :(
# * Upstream patch that adds the entry also nukes all of
# the versions before a project change (open-sourcing?)
# and as a result is 34K which is way too big just to fix this!
# * A stable URL to fetch this from works, but...
# * Upon inspection the resulting CHANGELOG is shorter
# than this comment, so while yes this is a bit gross
# adding these 4 lines here does the job without
# a huge patch in spirit of preferring upstream's fix
# instead of `sed -i 's/v0\.1\.0/v1.0.0/g' aom.pc` or so.
