Tagging the following updates for 21.X:
  - Made the BAT build not rely on RooStats. To make it a bit easier to use against custom-built ROOT versions.
  - Updated the way status messages are printed while the `atlas_project` function reads in the configuration of all packages. To make the printouts in a partial build less overwhelming.
  - Updated the ROOT build to use its built-in GSL version.
  - Updated AthAnalysisExternals and AthSimulationExternals not to build code in a multi-threaded way.

Tagging the 1.0 branch with the following updates since 1.0.15:
  - Synchronised Eigen to build the same version (3.2.9) that's in LCG_88;
  - Included various CMake updates in AtlasLCG;
  - Added the PyAnalysis package, to provide NumPy for AnalysisBase;
  - Added DMTCP to the AthDerivation externals (to keep AthenaMP functional once the 21.0 updates get merged in);
  - Added BAT to the available externals, to be used by AnalysisBaseExternals. (AnalysisTop most of all.)

Tag adding dmtcp to AthSimulationExternals, making AtlasLCG a bit more robust, and bringing
with it some documentation updates.

Tag fixing the python setup issues that crept into 1.0.13. Making it impossible
to build Gaudi on top of certain projects of the repository.

Tag introducing AthAnalysisExternals, and updating the analysis releases to LCG_88.
It also introduces FastJet-3.2.2, and makes AnalysisBaseExternals build Python on
MacOS X by default.

Upgrading to LCG_88, and some other updates.

This tag brings with itself LCG_88 for all LCG using projects,
a new external (dmtcp), and some dictionary generation fixes.

Tagging the updates to the dictionary handling code. Fixing the CI build issues
encountered recently.

Adding the setting of the TDAQ_PYTHON_HOME and TDAQ_VERSION variables to the runtime
environment for projects using tdaq-common and tdaq respectively.

Now explicitly setting the GCC optimisation flags for Debug, Release and RelWithDebInfo builds.

Tagging the FindXrootd.cmake fix, to make it easier to collect the new
version of the code into the 21.X builds.

Creating the first 21.X specific tag from the 1.0 branch. This should be in
sync with the externals that were compiled into AtlasExternals-21.0.20.

Creating the last tag before creating a separate branch for the 21.X releases
built from the athena repository.

Tagging the latest version with the GCC checker and ReleaseData
updates included.

Tagging the latest version, fixing a problem in the Boost build, and removing an incompatibility introduced for ZSH previously

Tagging the update to how the multi-versioned externals are set up for the build of the offline projects

Tagging the fix for the usage of mergeFiles.sh. So that the build wouldn't litter the source directory.

Creating a tag that could be used by the AnalysisBase project built from the master branch of atlas/athena as a start.

Creating the first tag of the repository. Which has a setup that is able to build the Athena project from the master branch of atlas/athena at the moment.
