I type in save and a name. It tells me, "No project selected". Oh K... I type in "list", and it tells me, "No projects". Fine then, dammit, maybe I cna name this thing, so I type "name thisprojectsomething", and it tells me.... wait for it... "No project selected". Goddammit, I'm screaming now, how the hell can I select a project then if you won't let me create one??! Where do projects *come* from, anyway, does the stork bring them?

rtm. README has a good example of how this works.
To get an idea of what it can do, I suggest doing this:

$ ./configure
$ make
# make install
$ lashd

then, in different consoles, run lash_panel and lash_synth.  Make
some Jack and Alsa Sequencer connections to the synth using aconnect and
jack_connect (or your patch bay of choice).

Play around with the settings of lash_synth, and click "Save Project" in the
control panel (you'll have to select a directory to save to).  Then click
"Close Project" and all running LASH clients should exit, and the project
tab in lash_panel should disappear.

Now use the "File->Open Session" menu item to open your saved project.  The
synth (and any other runnings LASH clients) should restart, and all the Jack
and Alsa MIDI connections should be restored.  Phat.
