Where is the OS Source?#

The OS source repository contains not just the kernel and the process manager, but also core libraries, services and utilities. This source repository holds it all!
A brief description of the source modules is available here.

Where are the good bits?#

The operating system (remember, by "operating system" or "procnto" we mean kernel and process manager) is comprised of the following pieces, each described on its own page:

Kernel#

Guide	Code
The Kernel Source Guide	/services/system/ker

Proc (aka the Process Manager)#

This provides the "process management" aspects of the system, including virtual memory and pathname management. It is the special process #1 multi-threaded server and is OS comprised of:

Guide	Code
The Memory Manager	/services/system/memmgr
The Path Manager	/services/system/pathmgr
The Process Manager	/services/system/procmgr and /services/system/proc

Public headers for the above, plus the kernel, are stored in /services/system/public.

The C Library (aka the clib or the glue)#

Guide	Source
Anatomy of the C Library	lib/c
