ok, a quick look at the source code shows that you have two options now:
1. use the userAppSupportDir
2. set an environment variable SC_SYNTHDEF_PATH, and this overrides
The work directory option apparently has disappeared... I can check if there
is an interest in adding it again with the other sc-devs.

On OSX there is an option to make a standalone version of the whole app, which
makes everything local to that version... maybe if we can come up with a
strategy how this could work for Linux (maybe also a static build of sclang,
scsynth and everything?), then we can make use of a similar way of
determining the resource paths as under OSX standalone...

On each OS, there is a userAppSupportDir, where files are stored or created
that are user specific. The actual path of these is different on each
platform. I think the specific name of "share" is relatively arbitrary, and
probably stems from Stefan Kersten's habit for local testing of things,
without installing things to /usr/local/.
As far as I am concerned it could indeed be called ~/.SuperCollider.

Some files are written by SC during runtime, so this has to be a directory to
which the user running the app can write to.
Also, the structure allows for users to customize their SC on a multi-user
system (e.g. as found in many schools), so that they can write their own
classes and put them somewhere without clogging other people's experience
with SC.

For bundling projects, or sets of extension classes, there is the Quark
system, which supports (or even assumes use of) svn, and allows you to
install those classes upon demand, by creating symlinks from the local copy
of the repository to the Extensions path.

Alternatively, you can either use a symlink for your classes to the home dir,
or use a config file to determine which classes are loaded and which not.

sincerely,
Marije
