Can you suggest a good introduction to Subversion for UNIX (or Mac OS X) users? It can assume familiarity with basic command-line usage, but not any advanced topics (with bash scripting counting as "advanced usage" here...)
Ideally, the guide should include:
a short introduction on what a VCS is for (in general) and to the Subversion model in particular;
quick-start usage (checkout, update/edit/commit cycle)
installation instructions; bonus points if it mentions that it's already available for all major OSes out there and leads people to install from package and not compile from source...
