'''links broken''' at 20050830

 Description: PRS has several Tcl/Tk downloadable items that are
        open source and free to use.  RTL is a runtime library
        collection of often used complex widgets which reduces
        the effort for developing sophisticated platform independant
        applications.  It includes a scrollable grid, input combobox,
        multiple column listbox, spinbox widget, shell widget,
        tree widget, and preferences widget.
        printerdll is an extension to let you print the contents of
        a Windows NT window.

[LV] however, if you use the search engine at http://www.prs.de/, you will 
find hits on RTL, including pointers to a download area.  I suggest
that in cases where people find broken links on a page, that if it is something
you really want, just email the company and see if they have moved the item.

Another possibily is using that www archive site - do we have a reference to it
here on the wiki?

''[escargo] 30 Aug 2005'' - I did not find pointers to a download area
when I did a search at their site (at least, not for RTL
specifically).  I also found references to a VisualGIPSY GUI designer released
as open source in 2000.  We really ought to find a home for open source code
that gets lost because the original developers abandon it (for whatever reason).
(Of course, if too much bit rot sets in, it wouldn't be much good, but one can hope.)

I have used the ''Wayback Machine'' at http://www.archive.org/ to find some past
pages, but I don't recall where I made the link.

Here's what the Wayback Machine found:
http://web.archive.org/web/20030622100705/http://www.prs.de/int/products/tcltkres/rtl/

Interesting the page title is "VisualGIPSY: RunTime Library". The last date the page was
recorded was October, 2004, but the copyright date on the page itself is 2000.

[LV] I'm surprised that the wayback machine doesn't change internal references to copies of the referenced pages that were there at the same time as the snapshot of the page.  By that I mean when I go to the archive.org link above, the download area link still points at prs.de, and the
page does not exist.

''[escargo] 30 Aug 2005'' - I think the reason that the Wayback Machine does not ''automatically''
update relative links is that it is not guessing which version of the link you want to follow.
I agree though, it would make sense for it to automatically make the links relative to the current
page.
