Directory open-wonka/awt

Apart from the ubiquitous Jamfile, this directory has three subdirectories:

oswald
The Reference Implementation of OSwald, an RTOS which can run either on bare hardware or as a "guest" of another operating system.
o4e
An implementation of the OSwald API in terms of the threading and memory management primitives of eCos, the Embedded Configurable Operating System from RedHat.
o4p
An implementation of the OSwald API in terms of "pthreads", the threading operations defined by POSIX, and malloc/free.
o4w
An implementation of the OSwald API in terms of the threading and memory management primitives of the Win32 API.

One or other directory will be included in the build according to the setting of the SCHEDULER variable (-sSCHEDULER=oswald, -sSCHEDULER=o4e or -sSCHEDULER=o4p).
