    Hello,<br>
    <br>I need to implement/integrate a command line interface
    (CLI) into a project<span id="result_box" class="" lang="en"><span class="">. <br><br></span></span>
    I have heard a lot of good things about the PETSc CLI and also I
    have found this old post talking a little about it:<br>
    <br>

    <br>
    I was looking for some information about PETSc CLI architecture or
    design pattern but i didn't find any information. <span id="result_box" class="" lang="en"><span class="">I also have</span>
      <span class="">been diving for</span> <span class="">the
        code,</span> <span class="">but  is not simple</span><span>..<br><br></span></span>
    
    <div style="display:inline-block" id="gt-input-tool">
      <div id="itamenu"><span class=""></span></div>
    </div>
    <div id="gt-src-c" class="">
      <div id="gt-src-p"> </div>
    </div>
    
      
        
        <span id="result_box" class="" lang="en"><span class="">Is
            there any</span> <span class="">document describing</span>
          <span class="">the architecture</span> <span class="">of</span>
          <span class="">PETSc</span> <span class="">CLI</span><span class="">? Can I have access to that information?<br>
            <br>
            Thanks in advance and congratulations for your great job
            with PETSc.<br>
            <br>
            Best regards,<br>
