/* actual implementation of our side of the LASH protocol */
/* NOTES: The LASH API, as it stands, is basically retarded. It was
* designed by retards for retards. The way it handles project state
* and project directories shows a deep lack of insight into how real
* software works. Since LASH doesn't provide us with the information
* we need--when we need it--we just punt and only use LASH to save
* and load the path to the *real* project data. One of these days a
* motivated individual (probably me, unfortuately) is going to spend
* a cozy afternoon implementing a replacement for LASH--a load of
* shit which has been in the works for God know how many years and is
* still stinking up the place. */
