haiku/headers/private/kernel/debug.h
Ingo Weinhold 8a90d12e26 * Added add_debugger_command_etc() which is similar to
add_debugger_command(), but additionally takes parameters "usage"
  and "flags".
* Added add_debugger_command_alias() which creates another name for an
  existing command.
* Added print_debugger_command_usage() to print a command's usage.
* invoke_debugger_command() intercepts invocations with "--help" and
  prints the command's usage text, if it is known. If unknown, the
  command will be called normally.
* Made use of the new functions in debug.cpp.
