Except that bzr-fast-export -> bzr-fast-import will produce similar
history but all revision ids will be different so you will not be able
to merge in bzr after you worked in git =/ so it will be read-only.
Marks files are used when you want to import multiple related bzr
branches into a git repo. So in general case you will not need it =)

Well I did this:

$ mkdir -p ~/.bazaar/plugins
$ bzr branch lp:bzr-fast-import ~/.bazaar/fast-import
$ bzr branch lp:xiphos
$ git init git-xiphos
$ cd git-xiphos
$ bzr fast-export ../xiphos | git fast-import

And the resulting git repository has master branch with tags.

Well I have my stupid reasons as well for choosing bzr for small
projects. With bzr-hg, bzr-git & bzr-svn I can work on all 4 without
doing a context switch. When I work on something big though like gcc
or binutils. Yeah git.... because of size & performance.

With bzr-* plugins though you generally get roundtrip & svn support is
excellent. On two machines bzr branch svn://URL will give identical
branches which you can merge between in bzr & svn, unlike git where
you have to use canonical import to have same SHA-1's on commits.
