# Gempub validator

Gempub is a new eBook format based on Gemini Protocol's Gemtext. Gempub can also serve as a Gemini capsule archive format. This program aims to validate a `gpub` file, if it is an archive it will verify that there is a `index.gmi` file at the root of the archive and if it is a book it will verify both `metadata.txt` and content.
