const char kClearShortHelp[] = "clear / cl: Clear a breakpoint.";
const char kClearHelp[] =
    R"(clear

  Alias: "cl"

  By itself, "clear" will delete the current active breakpoint.

  Clear a named breakpoint by specifying the breakpoint context for the
  command. Unlike GDB, the context comes first, so instead of "clear 2" to
  clear breakpoint #2, use "breakpoint 2 clear" (or "bp 2 cl" for short).

See also

  "help break": To create breakpoints.
  "help breakpoint": To manage the current breakpoint context.

Examples

  breakpoint 2 clear
  bp 2 cl
  clear
  cl
)";
