  As of 2022-03-31, the versioning for cartographer_ros is in a complicated situation.
  Upstream https://github.com/cartographer-project/cartographer_ros seems to be moribund,
  with no commits for close to a year.  The master branch there is only for ROS 1, and
  that branch has not had a released tag since 1.0.0 in 2018.

  In the meantime, we've done a port to ROS 2 in https://github.com/ros2/cartographer_ros
  that targets upstream cartographer 2.0.0.

  Since we have no response from upstream in a long time, we are going to go ahead and
  assume that the 1.x series of tags from upstream cartographer_ros will always be used
  to target ROS 1.  Further we are going to assume that the 2.x series of tags
  from upstream cartographer_ros (none of which exist yet) will be used to target ROS 2.
  If upstream comes alive and chooses a different versioning scheme, we can adjust later
  as necessary.  The outcome of all of this is that we are assuming a starting "upstream"
  release of 2.0.0, which then plays into the rest of the explanation below.

  We add 900 to the patch part of the version and then multiply it by 10,
  i.e. our version = `(upstream_patch_version + 900) * 10`,
  so we can have intermediate releases as well as release any future official 2.0.x versions.

  This is basically packing the patch part of the version and a fourth version part together
  into the third part of the version.

  The use of `900` instead of something else like `100` is arbitrary, but it might
  help people recognize that this is a "special" version number.
  It is needed however, because we cannot have a leading `0` in our patch version.

  Consider these possible future versions as an example:

  2.0.9000 -> current state of this repository, 2.0.0 + some commits from us
  2.0.9010 -> upstream 2.0.1
  2.0.9011 -> upstream 2.0.1 + additional commits from upstream or us
  2.0.9012 -> upstream 2.0.1 + additional commits from 2.0.1011 + more new commits
  2.0.9020 -> upstream 2.0.2
  and so on...

  <version>2.0.9003</version>
