[Vm-dev] Attempting to move Cog to Git(Hub)

[Fabio Niephaus]

Hi all,

I've been playing around with Cog to see what it'd take to move the code to
git.
GitHub's svn importer [1] isn't very reliable I think (some directories
were actually
missing), but eventually I managed to convert the entire svn repo to git
[2].

Also, I have been able to build different Cog VMs automatically on Travis
CI.
For a working build, see [3]. You can download the results at [4]. Please
keep
in mind that this is still a "test" ;)

Eliot was also concerned how the version info will be maintained and I have
a
simple proposal:

Each Cog release will be a git tag and for the version itself we could use
semantic versioning [3]. Then the build version is the git tag, the date is
the
commit date and the URL is the "remote.origin.url".

Here's an example:
====================================================================

Any further suggestions? :)

Best,
Fabio
