  <p>Breakpoints are used to stop the execution of the program at a particular
  point so that the state of the program can be examined at those locations.</p>

  <section>
    <title>Listing breakpoints</title>

    <steps>
      <item>
        <p>From the <gui>main menu</gui>, select <guiseq><gui>View</gui>
        <gui>Breakpoints</gui></guiseq> to open the <gui>Breakpoint</gui>
        window.</p>
      </item>
    </steps>

    <p>This view has the following columns:</p>
  
    <terms>
      <item>
        <title>Location</title>
        <p>This is the position of the breakpoint in the source file. When
        the breakpoint is set by the debugger, you can get additional
        information such as the function containing the breakpoint.</p>
      </item>
      <item>
        <title>Address</title>
        <p>This field is filled with the address of the breakpoint
        when it is set by the debugger.</p>
      </item>
      <item>
        <title>Type</title>
        <p>This always displays <gui>breakpoint</gui>. It will be used in a
        future release supporting different kinds of breakpoints.</p>
      </item>
      <item>
        <title>Condition</title>
        <p>This is the breakpoint condition. It is empty if no condition
        is defined.</p>
      </item>
      <item>
        <title>Pasaldi kopurua</title>
        <p>When the debugger is not running, this column displays the
        pass count of the breakpoint, or zero if it is not defined.</p>
        <p>When the debugger is running, if the pass count is zero,
        this column displays the number of times this breakpoint has
        been triggered. If the pass count is not zero, both numbers
        are displayed. The pass count is the second number.</p>
      </item>
      <item>
        <title>State</title>
        <p>This is the state of the breakpoint. It may be</p>
        <terms>
          <item><title>Pending:</title><p>the breakpoint is not set in your program.</p></item>
          <item><title>Permanent:</title><p>the breakpoint is set (its id number is displayed in parentheses).</p></item>
          <item><title>Temporary:</title><p>the breakpoint is set but will be deleted if reached.</p></item>
        </terms>
      </item>
    </terms>

    <note style="tip">
     <p>All breakpoints are kept across Anjuta sessions even if they correspond
     to a non-existing locations, for example in a source file of a shared library not
     loaded yet. In this case their states are set as pending.</p>

    <title>Setting breakpoints</title>

    <steps>
      <item>
        <p>From the <gui>main menu</gui>, select <guiseq><gui>Debug</gui>
        <gui>Add Breakpoint...</gui></guiseq> or right click in the
        <gui>Breakpoint</gui> window and select <gui>Add Breakpoint...</gui>.
        </p>
      </item>
      <item>
        <p>Fill in the <gui>Location</gui>, which is the position of the
        breakpoint, and the other fields if desired.
        If a file is currently opened in the editor, the <gui>Location</gui>
        defaults to the current line.
        See <link xref="debug-breakpoint-dialog"/> for more information.</p>
      </item>
    </steps>

    <p>Another solution is to use the toggle breakpoint function. If there
    is no breakpoint on the current line, it will add one. Otherwise, it will
    remove it.</p>

    <steps>
      <item>
        <p>From the <gui>main menu</gui>, select <guiseq><gui>Debug</gui>
        <gui>Toggle Breakpoint</gui></guiseq> or right click in the
        <gui>Editor</gui> window and select <gui>Toggle Breakpoint</gui>.
        </p>
      </item>
    </steps>

  </section>


  <section>
    <title>Editing breakpoints</title>

    <p>You can't change the location of a breakpoint; create a new breakpoint
    instead. However, you can change the break condition or the pass count. To
    edit a breakpoint:</p>

    <steps>
      <item>
        <p>Select a breakpoint in the <gui>Breakpoint</gui> window.</p>
      </item>
      <item>
        <p>Right click in the <gui>Breakpoint</gui> window and select
        <gui>Edit Breakpoint...</gui>.
        </p>
      </item>
      <item>
        <p>Change the <gui>Condition</gui> or <gui>Pass Count</gui>
        fields and click on <gui>OK</gui> when you are done.
        See <link xref="debug-breakpoint-dialog"/> for more information.</p>
      </item>
    </steps>

  <section>
    <title>Removing breakpoints</title>

	<p>You can remove a breakpoint using the toggle breakpoint function
	described above. However, if you want to remove more than one breakpoint
	or the breakpoint is in a different file than the one you are editing,
	you can use the breakpoint window:</p>

    <steps>
      <item>
        <p>Select a breakpoint in the <gui>Breakpoint</gui> window.</p>
      </item>
      <item>
        <p>Right click in the <gui>Breakpoint</gui> window and select
        <gui>Remove Breakpoint</gui>.
        </p>
      </item>
    </steps>

    <p>To remove all breakpoints:</p>

    <steps>
      <item>
        <p>From the <gui>main menu</gui>, select <guiseq><gui>Debug</gui>
        <gui>Remove All Breakpoints</gui></guiseq> or right-click in
        the <gui>Breakpoint</gui> window and select
        <gui>Remove All Breakpoints</gui>.</p>
      </item>
    </steps>

  </section>


  <section>
    <title>Enabling and disabling breakpoints</title>

    <p>Sometimes you might want to disable a breakpoint temporarily instead of
    deleting it altogether. To disable or re-enable a breakpoint:</p>

    <steps>
      <item>
        <p>Click on the <gui>Enable</gui> checkmark in the <gui>Breakpoint</gui>
        window or right click in the <gui>Breakpoint</gui> window and
        select <gui>Enable Breakpoint</gui> or <gui>Disable Breakpoint</gui>.</p>
      </item>
    </steps>

    <p>You can disable all breakpoints using:</p>

    <steps>
      <item>
        <p>From the <gui>main menu</gui>, select <guiseq><gui>Debug</gui>
        <gui>Disable All Breakpoints</gui></guiseq> or right-click in
        the <gui>Breakpoint</gui> window and select
        <gui>Disable All Breakpoints</gui>.</p>
      </item>
    </steps>
