[PATCH worg 0/2] Cleanup of LoB file

[~theophilusx]

These patches just perform some basic cleanup of the library-of-
babel.org file. It also moves a duplicate library-of-babel.org file into
the archive directory.  Note that I am working on a complete overhaul of
worg, which I will implement in a separate branch in my sourcehut clone
of the repo.

Given the planned changes are going to be fairly large, I felt it better
to do this work in a fork and separate branch on sourcehut, which chould
allow anyone interested to clone and review without affecting the main
worg repository. Happy to be added with write access to main worg
repository if you feel that is warranted, but probably don't really need
it at this point.

[PATCH worg 1/2] Move duplicate and obsolete LoB to archive

[~theophilusx]

From: Tim Cross <theophilusx@gmail.com>

A duplicate library-of-babel.org file was in the

worg/org-contrib/babel

directory. It was out-of-date, so I moved it to archive.
The 'real' library-of-babel.org file sits in the root /worg
directory.

From: Tim Cross <theophilusx@gmail.com>

- Add exmaple elispgantt test table and description

Still a bit of cleanup work required, but a start...

+** Example table of tasks and milestones for GANTT chart generation
+
+The following table describes the tasks and other relevant information for a project.  Each line is an /entry/ and there are three types of entry allowed in this table:
+
+- task :: an actual task that has a start time, a duration and an end time.
+- milestone :: a specific milestone in the project that has a start time alone
+- date :: a point in time that will be drawn as a vertical line in the GANTT chart (e.g. start of each year).
+
+Each element of the chart will be annotated with the content of the /label/ column of each entry.  The first column of the table is ignored but I use it to number the entries.  The last column, titled /align/, is used to determine where to place the /activity/ text for tasks, whether to the left or right of the bar or, if nothing is specified, centred within the bar itself.

Thank you very much!  I applied the patches on worg.

I also added you as a contributor to https://git.sr.ht/~bzg/worg/ so
that you can now push changes directly.

OK, thanks Bastien. Just out of interest, would you be able to send me a
copy of the nginx config for worg? I'm working on improving the build
process and I would like my local nginx to have a similar config. Also,
just in case there are changes which I think might improve the
experience from the server side, I would be good to know exactly what
the orgmode.org settings are. 

You can send that to me privately. It might even be worthwhile checking
it into the repository for reference.

Done, privately for now.

Thanks for any suggestions on how to also improve this configuration.
