# Azure template for installing dependencies from various package managers,
# necessary for building, testing, and packaging OpenTitan.
#
# This template can be included from pipelines in other repositories.
# In this case, set the the REPO_TOP parameter to point to the root of the
# checked out opentitan repository.
#
# This template executes:
# - apt-get (*) install for all packages listed in apt-requirements.txt
# - pip install for all packages listed in python-requirements.txt
#
# * As an optimization, apt-fast is used instead of apt-get if it is available.

      # properly parse Python-version metadata, which some packages uses to
      # specify that an older version of a package must be used for a certain
      # Python version. If that information is not read, pip installs the latest
      # version, which then fails to run.
