Conjugation

A set of tools for doing conjugation transformations in various languages. I will focus on keeping them to have similar usage patterns and types, to make integrating them easier.

Since I am tending to build off of prior work, each language may have different license conditions and usage. Please refer to the individual locale directories.

Import

This library is published to jsr.io, and can be used in various runtimes.
