     5Introduction
     6============
    47
    58This directory contains a stack bounds checker.  It provides two
     
    811   + check for stack overflow at each context switch
    912   + provides an educated guess at each task's stack usage
     13
     14Enabling
     15========
     16
     17Add the stack checker extension to the initial user extension set.
     18If using confdefs.h to build your configuration table, this is
     19as simple as adding -DSTACK_CHECK_ON to the gcc command line which
     20compiles the file defining the configuration table.  In the RTEMS
     21test suites and samples, this is always init.c
