I decided to give dune a try, mostly to give myself an excuse to
procrastinate with other projects.  After some rough going but being
able to figure it out, I hit what seems like an impassable strait.

dune generates the $package.opam file, therefore that file should not be
on version control.  _But_ then "opam pin ." insists on getting that
very file from the version control repo, instead of using the local one:

 matica!179 aaa$ opam pin .
[NOTE] Package aaa is already pinned to git+file:///home/itz/git/aaa#master (version 0.0.8~dev).
[aaa.0.0.8~dev] no changes from git+file:///home/itz/git/aaa#master
[WARNING] aaa's opam file has uncommitted changes, using the versioned one
aaa is now pinned to git+file:///home/itz/git/aaa#master (version 0.0.8~dev)
The following actions will be performed:
  - install aaa 0.0.8~dev*
Do you want to continue? [Y/n] y
[aaa.0.0.8~dev] synchronised from git+file:///home/itz/git/aaa#master

So how do you get around this?
