   what is the difference between Projector and guile-sdl ?

projector is no longer maintained.  the projector author contributed
code to guile-sdl, which then also went through a period of neglect
before finding new maintainership.

projector installation is a shared object library in ${libdir} (if i
recall correctly -- i played w/ it from the build dir w/o installing).
guile-sdl installation are compiled modules in ${libdir}/guile/site/sdl
(compiled modules are shared object libraries that follow certain

projector has fewer smob types (and hence less type checking) than
guile-sdl.  consequently projector is a bit faster and less memory-using
than guile-sdl but crashes more easily on uncareful code.

projector uses variables in most places where guile-sdl uses symbols
(event codes, keysyms, etc).

projector proc names begin with "sdl-" (usually, there are some
exceptions) while guile-sdl leaves prefixing to the user.

projector does not support ttf.

these are the things i can think of pre-coffee.  i have spiffed this
list and placed it on the guile-sdl home page.  updates from those w/
better memory (or more blood-bound caffeine) welcome.
