description: |
  Beremiz is an integrated development environment for machine automation. It is Free Software, conforming to IEC-61131 among other standards.

grade: devel
confinement: devmode
base: core20

parts:

  python-deps:
    # This part provides all python2 dependencies, including interpreter
    # More particularily, it builds latest PIP supporting python2 from git
    # and uses it to collect and buid other Beremiz dependencies.

    # rational:
    #  - python plugin doesn't support python2 anymore on core20+
    #  - attempts to get python2+pip+virtualenv in a core20 based snap failed
