Sorry to be the bearer of possibly bad news. It *seems* as if sinan
does not update its repo when a dependent release is updated. If it's
using the dependent release version number to discriminate, that might
be a bit dangerous during development. I thought it used an MD5
checksum of the tar file or something like that.

To reproduce the problem, I have uploaded to the files area test case
sinan project directory that has a dummy library release and a dummy
application that uses the library (sinan_test_case1.tar.gz).

$ tar xfz sinan_test_case1.tar.gz

$ cd sinan_test_case/mylib
$ sinan clean;sinan dist
$ faxien install-release
$ faxien publish (don't know if this step is needed)

$ cd ../myapp (makes use of mylib)
$ sinan clean;sinan release

Then make a change to an erl file in mylib, and go through the whole
cycle again. After this is done, do a directory of the sinan
repository and compare the beam files of mylib there to those under
mylib/_build. The repo is clearly out of date (see directory listing
at end of email).

Who cares? Well, if you innocently try to test the myapp build using
"sinan shell", you get to use the stale versions of the beam files IN
THE SINAN REPO (see below), NOT the installed versions or even the
most recently compiled ones. This does not seem right and certainly
violates the Principle Of Least Astonishment. Well, I was astonished
anyway.

$ sinan shell
