# Robustly modify metadata from command line

Right now, we're mostly manually editing files,
but it might be useful to do something like `xpit set XXX status=close`.
Right now, the obvious way to do that would be something like
`sed -i 's/status=closed/status=open/'`, which could cause unintended
side-effects in other parts of the file.

It might be more elegant to create a separate general utility to modify "code"
inside markdown files, maybe.
