# Test a dump created by cvs2git from a CVS repository with branches and
# tags.  Specifically, we're looking at the creation of a new branch
# REL-2-2-3 where the branch point is tagged REL-2-2-3-P1.

# Rather than create an artificial example, this is derived from
# a real-life CVS repository.

# This is the dump that cvs2git actually produces.  There are some
# oddities to it:
#  - commit 1619 has no first parent, but the "merge" directive
#    (second parent) points to the commit that should be its first parent
#  - commit 1620 should have 1619 as its first parent, but 1619 is
#    set to the second parent... and there is no first parent
#
# but git-fast-import accepts it, and the spec allows it.  Therefore,
# hg-fastimport must accept it and handle it correctly.
