const char kEnableShortHelp[] = "enable: Enable a breakpoint.";
const char kEnableHelp[] =
    R"(enable

  By itself, "enable" will enable the current active breakpoint. It is the
  opposite of "disable".

  It can be combined with an explicit breakpoint prefix to indicate a specific
  breakpoint to enable.

  It is an alias for:

    bp set enabled = true

See also

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

Examples

  breakpoint 2 enable
  bp 2 enable
      Enable a specific breakpoint.

  enable
      Enable the current breakpoint.
