Just a suggestion from me, calling tbot like this:

  tbot -c config.ini my-testcase

Where the ini file would contain something like this:

  [tbot]
  verbose=2
  cwd=/home/user/work/tbot/tbot-myproduct
  lab=lab/my-lab.py
  board=board/my-board.py
  flags=flag1 flag2
  testcase=my-default-testcase

  [project]
  sources=work/source/my-project-source
  outdir=work/source/my-project-source/out
  nfsdir=/srv/nfs/my-project/user/
  tftpdir=/srv/tftp/my-project/user/

What do you think?
