SIG Doc builder

This script will generate the following documentation files:

sig-*/README.md
sig-list.md

Based off the sigs.yaml metadata file.

How to use

To (re)build documentation for all the SIGs, run these commands:

make all

## Adding custom content to your SIG's README

If your SIG wishes to add custom content, you can do so by placing it within the following code comments:

<!-- BEGIN CUSTOM CONTENT -->

<!-- END CUSTOM CONTENT -->

Anything inside these code comments are saved by the generator and appended to newly generated content. Updating any content outside this block, however, will be overwritten the next time the generator runs.

An example might be:

<!-- BEGIN CUSTOM CONTENT -->
## Upcoming SIG goals
- Do this
- Do that
<!-- END CUSTOM CONTENT -->
