-@REM This bat file has been generated by the IAR Embeddded Workbench
-@REM C-SPY interactive debugger,as an aid to preparing a command
-@REM line for running the cspybat command line utility with the
-@REM appropriate settings.
-@REM
-@REM After making some adjustments to this file, you can launch cspybat
-@REM by typing the name of this file followed by the name of the debug
-@REM file (usually an ubrof file). Note that this file is generated
-@REM every time a new debug session is initialized, so you may want to
-@REM move or rename the file before making changes.
-@REM
-@REM Note: some command line arguments cannot be properly generated
-@REM by this process. Specifically, the plugin which is responsible
-@REM for the Terminal I/O window (and other C runtime functionality)
-@REM comes in a special version for cspybat, and the name of that
-@REM plugin dll is not known when generating this file. It resides in
-@REM the $TOOLKIT_DIR$\bin folder and is usually called XXXbat.dll or
-@REM XXXlibsupportbat.dll, where XXX is the name of the corresponding
-@REM tool chain. Replace the '<libsupport_plugin>' parameter
-@REM below with the appropriate file name. Other plugins loaded by
-@REM C-SPY are usually not needed by, or will not work in, cspybat
-@REM but they are listed at the end of this file for reference.
