Klever

Today Evgeny sent me the following error trace associated with Clade:

File "/home/novikov/work/klever/core/core/pfg/abstractions/__init__.py", line 355, in __divide
    for desc in (d for d in self.clade.compilation_cmds if d.get('out') and len(d.get('out')) > 0):
  File "/home/novikov/work/klever/venv/lib/python3.6/site-packages/clade/__init__.py", line 307, in compilation_cmds

  File "/home/novikov/work/klever/venv/lib/python3.6/site-packages/clade/extensions/path.py", line 58, in get_rel_path
    raise RuntimeError

The reason of the error is that the installed version of Clade was incompatible with the build base. But as mentioned in this ticket, such incompatibility can be easily detected beforehand by using available Clade API described in https://github.com/17451k/clade/issues/108. It would be fairly easy to implement and benefits are clear, so I advise you to do it right away!
