positive.code: 2. In Linux, side-by-side, by python tools fast-export

  cd ~/dev/
  git clone git://repo.or.cz/fast-export.git
  git init git_repo
  cd git_repo
  ~/dev/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo
  git checkout HEAD
  
  Problems:
  2.1. unnamed heads
  - can be resolved by '--force' switch for fast-export
  - WON'T be converted to git
  2.2. hidden changesets
  - they are created if hg was using evolve extension (maybe when executing rebase?)
  - fast-export don't support these
  - they must be deleted from hg repo before conversion
