[Beowulf] Thoughts on git?

[John Hearns]

Nathan, Sir - you are a prize Git.
Abusive retorts aside, there is another very good use for Git.

As a fan of the Julia language, I report that Julia packages are held as
repositories on Github.
If you want to work with an unregistered package (which is usually a
development project)
you bring the package onto your system using a 'git clone'.

I'm not really sure how you would then cope with a secure site with no
Internet access.
Last time I had to install RPM updates on a Government secure site we
cloned the repository to a hard drive
and brought it onto site. It is easy enough to make a local clone of a Git
repo on a hard drive.
I guess I should ask on the Julia list how to use that as a repo for
packages.
