_Dbg_help_add commands \
'commands [BKPT-NUM]

Set commands to be executed when a breakpoint is hit.

Without BKPT-NUM, the targeted breakpoint is the last one set.  The
commands themselves follow starting on the next line.  

Type a line containing "end" to indicate the end of them.  Give
"silent" as the first line to make the breakpoint silent; then no
output is printed when it is hit, except what the commands print.'
