## Features

The package supports drawing timelines and aims to be highly customisable. 
Extensive configuration options are offered via a standard key-value interface 
based on pgfkeys. Custom colour schemes and styles are supported, and the 
package includes documented examples of each. Memoization works out-of-the-box 
if the memoize package is loaded. The code was developed as a result of 
questions concerning difficulties in customising the output of existing packages 
for drawing timelines, which sometimes eschew pgfkeys and are often challenging 
to configure, even when based on PGF/TikZ.

chronos is based on TikZ, but uses some functions from expl3.
