  127. <p><small>GDB/MI</small> is a line based machine oriented text interface to

  128. <small>GDB</small> and is activated by specifying using the

  129. <samp>--interpreter</samp> command line option (see <a href="Mode-Options.html#Mode-Options">Mode Options</a>).  It

  130. is specifically intended to support the development of systems which

  131. use the debugger as just one small component of a larger system.

  132. </p>

  133. <p>This chapter is a specification of the <small>GDB/MI</small> interface.  It is written

  134. in the form of a reference manual.

  135. </p>

  136. <p>Note that <small>GDB/MI</small> is still under construction, so some of the

  137. features described below are incomplete and subject to change
