-This package is an extension to `pymatgen` for performing I/O validation. Specifically, this package checks for discrepancies with a provided input set, known bugs when certain input parameters are used in combination, and several other small checks. The initial motivation for creating this package was to validate calculations performed by groups outside of the Materials Project (MP), enabling their raw data to be included in the MP Database.
