How to extract the drawing summary info using AutoLISP?

Question
I added drawing properties (summary info) to some drawings using the DWGPROPS
command. How do I extract this information using AutoLISP?
Answer
The summary information is stored in a dictionary called "DWGPROPS".

The first thing you need to do is test if the drawing contains the DWGPROPS
dictionary.
If the dictionary does not exist, the summary information is not stored in the
drawing.

If this dictionary exists, you need to obtain it so that you can extract the
group codes you want from fields in the DWGPROPS dialog.

The following lists the used group codes:

2 Title
3 Subject
4 Author
6 Comments
7 Keywords
1 Hyperlink
8 Last saved by
9 Revision
40 Editing time
41 Creation time
42 Last modified time
90 Number of custom properties
300-
309 Custom properties

NOTE: Group code 1 is used two times in the dictionary. The Hyperlink is stored
in the second one. The time values are specified in the Julian date/time format.
Look at the Julian.lsp file in AutoCAD to see how to convert this format into a
'readable' format.

The following AutoLISP function extracts the summary information from the
current drawing (it does not convert the time values):
