[bug#74806] [WIP PATCH] gnu: python-mathics-core: Add docs.

[Danny Milosavljevic]

I would like help fixing a build failure here (latexmk parallelism problem):

! Undefined control sequence.
l.289 \InputIfFile

./source/mathics/doc/latex/mathics.pre:

  \InputIfFileExists {\jobname -281.pre}{}{}
  \InputIfFileExists {\jobname -282.pre}{}{}
  \InputIfFileExists {\jobname -283.pre}{}{}
  \InputIfFileExists {\jobname -284.pre}{}{}
  \InputIfFileExists {\jobname -285.pre}{}{}
  \InputIfFileExists {\jobname -286.pre}{}{}
  \InputIfFileExists {\jobname -287.pre}{}{}
  \InputIfFileExists {\jobname -288.pre}{}{}
  \InputIfFile

(ed note: Cut off in the original)

* gnu/packages/plotutils.scm (asymptote): Install files where latex will find them.
* gnu/packages/maths.scm (python-mathics-core): Add docs.
