      Create a list of language codes and names so it can be sorted.
      Jumping through hoops so that the new lines and spaces from the case are removed at the start of the names.
      Finally the array is sorted, which is possible because each entry is now guaranteed to start with the language name, no whitespace.
      Whitespaces still need to be filtered before outputing the strings.

  <h3>Absolute Newest</h3>
  <p>
    Every time we commit new code to CircuitPython we automatically
    build binaries for each board and language.  The binaries are
    stored on Amazon S3, organized by board, and then by
    language. Try them if you want the absolute latest and are
    feeling daring or want to see if a problem has been fixed.

  <h3>Past Releases</h3>
  <p>
    All previous releases are listed on GitHub, with release notes,
    and are available for download from Amazon S3.  They are handy for
    testing, but otherwise we recommend using the latest stable
    release.  Some older GitHub release pages include the same
    binaries for downloading.  But we have discontinued including
    binaries as assets on newer release pages because of the large
    number of files for each release.

Only output bootloader information if we have complete info about a board, and we know the latest

By the way, boolean operation precedence is right to left! (yeesh)

  <h3>Install, Repair, or Update UF2 Bootloader</h3>
  <p>
    Latest version: {{ bootloader_version }}
  </p>
  <p>
    <strong>The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs.
      The bootloader is not CircuitPython.</strong>
    If a UF2 bootloader is installed, you can check its version by looking in
    the <b>INFO_UF2.TXT</b> file when the <b>BOOT</b> drive is visible
    (<b>FTHRS2BOOT</b>, <b>MAGTAGBOOT</b>, <b>HOUSEBOOT</b>, etc.)
  </p>
  <p>
    It is not necessary to reinstall a UF2 bootloader you unless a <b>BOOT</b> drive is not visible
    when in UF2 bootloader mode, or you know of a problem with your current UF2 bootloader.
  </p>
  <p>
    If a UF2 bootloader has never been installed on the board, or the UF2 bootloader was removed by erasing or overwriting the flash, the UF2 bootloader must be installed in order to flash <b>.uf2</b> files onto the board. <b>.bin</b> files can be uploaded without a UF2 bootloader, using the
    <a href="https://nabucasa.github.io/esp-web-flasher/">ESP Web Flasher</a>
    or <b>esptool.py</b>.
  </p>

  <p>
    <em>Note: <b>update.uf2</b> files are not currently working on ESP32-S2 or ESP32-S3 boards.</em>
  </p>

  <p><strong><em>Important</em></strong>:
    <em>this will erase previously flashed firmware and sketches from the board,
      but needs to be perfomed only once.</em>
  </p>
  <p><em>The instructions here are general.
      We recommend you consult the manufacturer's board documentation for detailed
      instructions, which may be different.</em>
  </p>
 <ul>
  <li>Unzip to find the file <b>combined.bin</b>.</li>
  <li>Place board in bootloader mode:
   <ul>
    <li>Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.</li>
    <li>Press and <strong>hold down</strong> the <b>BOOT</b> or <b>0</b> button.</li>
    <li>Press and <strong>release</strong> the <b>RESET</b> or <b>RST</b> button.</li>
    <li>Release the <b>BOOT</b> button.</li>
   </ul>
  </li>
  <li>Upload <b>combined.bin</b> (Google Chrome 89 or newer):
   <ul>
    <li>Open <a href="https://nabucasa.github.io/esp-web-flasher/">ESP Web Flasher</a> in a new window/tab.</li>
    <li>Select <b>460800 Baud</b> from the pull-down menu (top-right).</li>
    <li>Click <b>Connect</b> (top-right).</li>
    <li>Select the COM or Serial port from the pop-up window.</li>
    <li>After successful connection, click <b>Erase</b>.</li>
    <li>After successful erase, click any <b>Choose a file...</b>, then locate and select the <b>combined.bin</b> file unzipped earlier.</li>
    <li>After successfully choosing <b>combined.bin</b>, click <b>Program</b>.</li>
    <li>After the TinyUF2 firmware update is complete, press the <b>RESET</b> button on the board.
      A new drive <b>BOOT</b> should be visible in your file browser.</li>
   </ul>
  </li>
 </ul>
 <p>
   After installing the UF2 bootloader, enter the bootloader by double-clicking the reset button.
   On boards with an RGB status LED, tap reset once, wait for the LED to turn purple, and tap
   again before the purple goes away. On other boards, consult the board documentation.
   </p>
 <p>
   After you update, check <b>INFO_UF2.TXT</b> to verify that the bootloader version has been updated.
   Then you will need to load or reload CircuitPython using the <b>.uf2</b> file.

    <strong>The bootloader allows you to load CircuitPython, MakeCode, and Arduino programs.

    You can check the current version of your bootloader by looking in

  </p>
  <p>
    It is not necessary to update your bootloader if it is working fine.
    Read the release notes on GitHub to see what has been changed.
    In general, we recommend you not update the bootloader unless you know there is a problem with it

    Updating the bootloader on nRF52840 boards is an involved process right now.
    Follow the instructions in this
    <a href="https://github.com/adafruit/Adafruit_nRF52_Bootloader/blob/master/README.md">README</a>.
  </p>
  <p>
    After you update, check <b>INFO_UF2.TXT</b> to verify that the bootloader version has been updated.

    To update, first save the contents of <b>CIRCUITPY</b>, just in case.
    Then double-click the reset button to show the <b>BOOT</b> drive.
    Drag the <b>update-bootloader</b> <b>.uf2</b> file to the <b>BOOT</b> drive.
    Wait a few tens of seconds for the bootloader to update; the <b>BOOT</b> drive will reappear.
    After you update, check <b>INFO_UF2.TXT</b> to verify that the bootloader version has been updated.
    Then you will need to reload CircuitPython.
