Summary description: Download, access, and potentially execute files from git

Announcement text: ----------------------------------------------------------------------

The “texgit” package is a tool mainly intended for including source
codes and files from external “git” repositories in LaTeX code.
Imagine that you are teacher in the field of computer science.
Maybe you are teaching a programming class.
You want to use LaTeX to make a course book or course slides.
Naturally, you will want to include example programs and source
codes in your book/slides.
Maybe you even want to execute your codes and show their outputs.
That is, at present, tedious.
You could put them as files into your teaching material and manually
execute them.
But they will always be isolated examples and more often than not,
code examples are just written directly in the LaTeX sources in
listings environments.

With the “texgit” package, you can separate your example codes
from your teaching material.
You can put them into a separate “git” repository.
In your LaTeX code, you can tell “texgit” to download this
repository (it will be cached locally) and then get the local
paths to the files in the repository.
Moreover, you can also execute the downloaded files and let
“texgit” store their output into local files (which, again,
will be cached).
You can then include these files in your teaching material.

The “texgit” package allows you to do the following things:
- download files from a “git” repository and access them from LaTeX,
- apply some post-processor to the downloaded files (e.g., strip comments
and type hints from Python code) and access the post-processed files instead,
- execute scripts or programs -- either local or downloaded from “git”
repositories -- and fetch their output into local files accessible from LaTeX,
- create local paths accessible from LaTeX which can be passed as
arguments to the scripts or programs that are executed, e.g., as
argument to a Python script that creates and stores a “matplotlib”
plot under the path that it received as argument, allowing you to
programmatically create figures and include them LaTeX documents.

The package works a bit like “BibTeX”:
Let’s say your document is named “document.tex”.
During the first “pdflatex” run, executed as “pdflatex document”,
all the requests mentioned above, say, to download files from
“git” repositories, are stored in the “aux” file.
The paths corresponding to the requests point to an empty file
at this stage.
Then you would apply the “texgit” post-processor by calling
“python3 -m texgit.run document”.
This Python program (see https://pypi.org/project/texgit) executes
all the requests and caches their results locally.
During the second run of “pdflatex document”, the paths
corresponding to the requests then point to the actual
downloaded or generated files.

All downloaded or generated files will be locally cached
in a folder named “__git__” in your document’s directory.
You can delete this folder to refresh the files.
