Cure to Golden Ratio OCD on Humble Bundle

_readme.md

Set the humble bundle payment portions to follow golden ratio

TLDR

1. Copy paste the content from bundlecalculator.min.js into developer console.
2. Run set_ratio(15). Replace 15 to any figure you wish to pay.

Additional parameters

Disable full allocation to user selected charity

Enabled by default. To disable the behaviour, set second parameter to false, e.g. set_ratio(15, false).

Show debug

Disabled by default. To enable debug message, set third parameter to true set_ratio(15, false, true).

Changing the distribution

The default order from highest to lowest is: Developer/Publisher, Charity, Humble Bundle. If you wish to change it to for example, Charity, Developer/Publisher, Humble Bundle; run set_ratio(15, false, false, 1, 0, 2)
