Convert SVG to SCE via CLI?

[NathanUp]

I'm wondering if there is a way to convert SVG files to SVE through the terminal on GNU/Linux (or the other way around)- The reason is this:

Both Krita and Inkscape use SVG files in special directories to populate their "symbols" panels, which store graphics across sessions for later use, much like Scribus' scrapbook panel. If it were possible to create an SCE from an SVG in the terminal, I could write a script that would parse an SVG file and create a Scribus scrapbook programmatically from the symbols contained in it.

A tool like this would allow a user to create a library of symbols / scrapbook items once and then have all of those assets available across Scribus, Krita, and Inkscape with the click of a button.
