 This package is a Julia complement to [LyoPRONTO](https://github.com/LyoHUB/LyoPronto), an open source Python package.
 It has some overlapping functionality with LyoPRONTO, especially simulation of primary drying for conventional lyophilization.
 LyoPRONTO (the Python version) also has functionality for generating a design space, estimating time to freeze, and picking optimal drying conditions.
-On the other hand, this package has much more advanced utilities for fitting empirical parameters (such as $R_p$ and $K_v$) to experimental data.
