Re: Checkout without storing two copies

@Ryan Schmidt @Stefan Sperling. I guess that the difficulty of
implementing this depends on how much of the client code depends on
the existence of those files. From the linked bug tracker item, the
answer appears to be 'quite a lot', though I don't know anything about
this codebase.

@Paul Hammant This is used by myself only and I am familiar with
working with SVN and GIT on the command line, but in no way an
'expert'. I prefer tools which are simple and developer focused and
use Linux exclusively, prefer text file configuration.

I mainly work on a desktop but sometimes need to move part of the
file-system onto a laptop and then merge it back again. By file size
most of this data is DSLR raw files and source video, most of which is
related to a website with associated source code. Additionally I have
multiple unrelated personal projects from the past 7 years which need
to be in there own repositories. And miscellaneous 'stuff' which also
needs to stay separate. Some files are interdependent, some are not.

I too have developed a tool to fit my needs, having become
sufficiently frustrated with other tools. However I feel that I'm just
reimplementing part of Subversion, hence the question.

The implementation of this system is very naive, for example storing
it's file manifest as JSON. It also has a number of problems that I
haven't fixed yet. However I've been quite surprised at how well it
works. It handles 16,000 individual files in one of my projects
without difficulty, the biggest bottleneck being the network.
Currently I'm using this to manage the binary stuff and git for code.

I was surprised how easy it was to implement this. The above system is
just over 1000 lines of python and a good chunk of that is a
journaling file-system interface.
