# Rules of src

## Optimizations

Best to run this with pypy3

## Using global options

Files needing global options start with `from choice import *`.

Global options are read into class static variables using, eg.


```
class num:
  hedges = our.num.hedges # 0.38
  conf   = our.num.conf   # 0.95
  
```

Thereafter, code needed the options talks to `className.var` and not
`our.x.y`. Why?  Well, if you are sick of my global system, then dump it and
make all the config static class variables.
