/* usrConfig.c - user-defined system configuration library */


/*
DESCRIPTION
This library is the WRS-supplied configuration module for VxWorks.  It
contains the root task, the primary system initialization routine, the
network initialization routine, and the clock interrupt routine.

The include file config.h includes a number of system-dependent parameters used
in this file.

In an effort to simplify the presentation of the configuration of vxWorks,
this file has been split into smaller files.  These additional configuration
source files are located in ../../src/config/usr[xxx].c and are #included into
this file below.  This file contains the bulk of the code a customer is
likely to customize.

The module usrDepend.c contains checks that guard against unsupported
configurations such as INCLUDE_NFS without INCLUDE_RPC.  The module
usrKernel.c contains the core initialization of the kernel which is rarely
customized, but provided for information.  The module usrNetwork.c now
contains all network initialization code.  Finally, the module usrExtra.c
contains the conditional inclusion of the optional packages selected in
configAll.h.

The source code necessary for the configuration selected is entirely
included in this file during compilation as part of a standard build in
the board support package.  No other make is necessary.
