once is a Node.js module to call a function exactly one time. Subsequent calls will either return the cached previous value or throw an error if desired.

This package provides a zip library for Node. It follows the following principles:

1. Don't block the JavaScript thread. Use and provide async APIs.

2. Keep memory usage under control. Don't attempt to buffer entire files in RAM at once.

3. Prefer to open input files one at a time than all at once.

Simulate DNA sequences for the node substitution model. In the node substitution model, substitutions accumulate additionally during a speciation event, providing a potential mechanistic explanation for substitution rate variation. This package provides tools to simulate such a process, simulate a reference process with only substitutions along the branches, and provides tools to infer phylogenies from alignments.
