+ * In the following is listed more documentation about the Shell Link file format,
+ * as well as its interface.
+ *
+ * General introduction about "Shell Links" (MSDN):
+ * https://msdn.microsoft.com/en-us/library/windows/desktop/bb776891(v=vs.85).aspx
+ *
+ *
+ * Details of the file format:
+ *
+ * - Official MSDN documentation "[MS-SHLLINK]: Shell Link (.LNK) Binary File Format":
+ * https://msdn.microsoft.com/en-us/library/dd871305.aspx
+ *
+ * - Forensics:
+ * http://forensicswiki.org/wiki/LNK
+ * http://computerforensics.parsonage.co.uk/downloads/TheMeaningofLIFE.pdf
+ * https://ithreats.files.wordpress.com/2009/05/lnk_the_windows_shortcut_file_format.pdf
+ * https://github.com/libyal/liblnk/blob/master/documentation/Windows%20Shortcut%20File%20(LNK)%20format.asciidoc
+ *
+ * - List of possible shell link header flags (SHELL_LINK_DATA_FLAGS enumeration):
+ * https://msdn.microsoft.com/en-us/library/windows/desktop/bb762540(v=vs.85).aspx
+ * https://msdn.microsoft.com/en-us/library/dd891314.aspx
+ *
+ *
+ * In addition to storing its target by using a PIDL, a shell link file also
+ * stores metadata to make the shell able to track the link target, in situations
+ * where the link target is moved amongst local or network directories, or moved
+ * to different volumes. For this, two structures are used:
+ *
+ * - The first and oldest one (from NewShell/WinNT4) is the "LinkInfo" structure,
+ * stored in a serialized manner at the beginning of the shell link file:
+ * https://msdn.microsoft.com/en-us/library/dd871404.aspx
+ * The official API for manipulating this is located in LINKINFO.DLL .
+ *
+ * - The second, more recent one, is an extra binary block appended to the
+ * extra-data list of the shell link file: this is the "TrackerDataBlock":
+ * https://msdn.microsoft.com/en-us/library/dd891376.aspx
+ * Its purpose is for link tracking, and works in coordination with the
+ * "Distributed Link Tracking" service ('TrkWks' client, 'TrkSvr' server).
+ * See a detailed explanation at:
+ * http://www.serverwatch.com/tutorials/article.php/1476701/Searching-for-the-Missing-Link-Distributed-Link-Tracking.htm
+ *
+ *
+ * MSI installations most of the time create so-called "advertised shortcuts".
+ * They provide an icon for a program that may not be installed yet, and invoke
+ * MSI to install the program when the shortcut is opened (resolved).
+ * The philosophy of this approach is explained in detail inside the MSDN article
+ * "Application Resiliency: Unlock the Hidden Features of Windows Installer"
+ * (by Michael Sanford), here:
+ * https://msdn.microsoft.com/en-us/library/aa302344.aspx
+ *
+ * This functionality is implemented by adding a binary "Darwin" data block
+ * of type "EXP_DARWIN_LINK", signature EXP_DARWIN_ID_SIG == 0xA0000006,
+ * to the shell link file:
+ * https://msdn.microsoft.com/en-us/library/dd871369.aspx
+ * or, this could be done more simply by specifying a special link target path
+ * with the IShellLink::SetPath() function. Defining the following GUID:
+ * SHELL32_AdvtShortcutComponent = "::{9db1186e-40df-11d1-aa8c-00c04fb67863}:"
+ * setting a target of the form:
+ * "::{SHELL32_AdvtShortcutComponent}:<MSI_App_ID>"
+ * would automatically create the necessary binary block.
+ *
+ * With that, the target of the shortcut now becomes the MSI data. The latter
+ * is parsed from MSI and retrieved by the shell that then can run the program.
+ *
+ * This MSI functionality, dubbed "link blessing", actually originates from an
+ * older technology introduced in Internet Explorer 3 (and now obsolete since
+ * Internet Explorer 7), called "MS Internet Component Download (MSICD)", see
+ * this MSDN introductory article:
+ * https://msdn.microsoft.com/en-us/library/aa741198(v=vs.85).aspx
+ * and leveraged in Internet Explorer 4 with "Software Update Channels", see:
+ * https://msdn.microsoft.com/en-us/library/aa740931(v=vs.85).aspx
+ * Applications supporting this technology could present shell links having
+ * a special target, see subsection "Modifying the Shortcut" in the article:
+ * https://msdn.microsoft.com/en-us/library/aa741201(v=vs.85).aspx#pub_shor
+ *
+ * Similarly as for the MSI shortcuts, these MSICD shortcuts are created by
+ * specifying a special link target path with the IShellLink::SetPath() function,
+ * defining the following GUID:
+ * SHELL32_AdvtShortcutProduct = "::{9db1186f-40df-11d1-aa8c-00c04fb67863}:"
+ * and setting a target of the form:
+ * "::{SHELL32_AdvtShortcutProduct}:<AppName>::<Path>" .
+ * A tool, called "blesslnk.exe", was also provided for automatizing the process;
+ * its ReadMe can be found in the (now outdated) MS "Internet Client SDK" (INetSDK,
+ * for MS Windows 95 and NT), whose contents can be read at:
+ * http://www.msfn.org/board/topic/145352-new-windows-lnk-vulnerability/?page=4#comment-944223
+ * The MS INetSDK can be found at:
+ * https://web.archive.org/web/20100924000013/http://support.microsoft.com/kb/177877
+ *
+ * Internally the shell link target of these MSICD shortcuts is converted into
+ * a binary data block of a type similar to Darwin / "EXP_DARWIN_LINK", but with
+ * a different signature EXP_LOGO3_ID_SIG == 0xA0000007 . Such shell links are
+ * called "Logo3" shortcuts. They were evoked in this user comment in "The Old
+ * New Thing" blog:
+ * https://blogs.msdn.microsoft.com/oldnewthing/20121210-00/?p=5883#comment-1025083
+ *
+ * The shell exports the API 'SoftwareUpdateMessageBox' (in shdocvw.dll) that
+ * displays a message when an update for an application supporting this
+ * technology is available.
