+@code{SIMPLE-DATE} is a very basic implementation of date and time objects, used

+
+@code{S-SQL} is used to compile s-expressions to strings of SQL code, escaping
+any Lisp values inside, and doing as much as possible of the work at compile
+time.
+
+@code{CL-POSTGRES} is the low-level library used for interfacing with a PostgreSQL
+server over a socket.
+
+@code{POSTMODERN} itself is a wrapper around these packages and provides higher

+Author: Reiner Herrmann <reiner@reiner-h.de>
+Description: Disable downloaders
+ This makes porting to Qt5 much easier, as QHttp is no longer available.
+ But the functionality was not enabled anyway or is no longer useful.
+ .
+ - checkversion.h/.cpp:
+   At startup (while loading settings), Tipp10 "phones home" to do an
+   update check (www.tipp10.com/update/version.tipp10v210).
+   For a packaged software and one that is no longer being developed,
+   this does not make much sense.
+ - updatedialog.h/.cpp:
+   Can download newer sqlite database (www.tipp10.com/update/sql.tipp10v210.utf),
+   but this file is no longer available on the server (404).
+   The update action has also not been enabled in the menu, so the update
+   functionality was currently not active:
+     widget/mainwindow.cpp:143:  //fileMenu->addAction(updateAction);
+ - downloaddialog.h/.cpp:
+   Allows downloading lessons from user-specified location.
+   But the action (widget/startwidget.cpp -> lessonDownload) has not been part
+   of any menu, so it was also not in use.

+bookmarks or hyperlinks.
+
+When Ghostscript reads the main PDF generated by the TeX system with embedded
+PDF files and outputs the final PDF, the PDF page mode and name targets
+etc. are not preserved.  Therefore, when you open the final PDF, it is not
+displayed correctly.  Also, remote PDF links do not work correctly.
+
+This program is able to extract the page mode and named targets as PDFmark
+from PDF.  In this way, you can obtain embedded PDF files that have kept this
+information.")
