sockets Examples for the new built-in module 'socket'.
sgi Demos that only run on Silicon Graphics machines.
- Require the built-in modules 'audio' and/or 'gl'
- and/or 'stdwin'.
- (This is split in corresponding subdirectories.)
+ These require at least one of the optional built-in
+ modules that only make sense for the SGI, such as
+ the modules 'gl' and 'al'. Split in subdirectories
+ per subject.
stdwin Demos that use the STDWIN library. Require the 'stdwin'
built-in module.
