# This command sorts by reversed filenames, which places files

# Help create a pyproject.toml from a setup.py file
# 
# USAGE:
#   1)
#     replace "from [a-z.]* import setup" in your setup.py 
#     with "from convert_setup_py_to_pyproject_toml import setup"
#   2)
#     run the resulting script with python, with this script in the PYTHONPATH
#   
#   The above can be achieved on Linux, for example, with:

"""Package a paper written in latex for arxiv.
 
Rationale
---------

You may have figures and bibliography included from somewhere else in your file system with absolute paths.
This script makes a subdirectory package-mylatexfile.tex/ which contains the latex file, figures, .bib, input files referenced in the tex file
in the subdirectory, pdflatex mylatexfile.tex should work and not touch any files outside the subdirectory.
the subdirectory can then by tarred and uploaded to arxiv.
