How to test how much more memory the docs build will consume as collections are added

instructions.txt

* Checkout ansible-build-data 
  * git clone https://github.com/ansible-community/ansible-build-data
* For testing the devel tree, modify the latest ansible.in file (currently ansible-build-data/5/ansible.in)
  * Example, this adds the community.dns collection to the collection docs that will be built:
  * echo 'community.dns ' >> ansible-build-data/5/ansible.in
* For testing the stable tree, you will have to modify the latest ansible-X.Y.Z.deps file:
  * echo 'community.dns: 1.0.1' >> ansible-build-data/4/ansible-4.2.0.deps
* Download the patch to ansible-core:
  * wget https://github.com/ansible/ansible/pull/75150.patch
* Checkout the ansible-core code:
  * git clone https://github.com/ansible/ansible
* cd ansible
* apply the patch to your checkout:
  * git apply ../75150.patch
* Tell the docs build to use your local copy of ansible-build-data when building the ansible package devel docs:
  * Note: the ansible-build-data path can be absolute.  If relative as in the example, it is relative to the ansible/docs/docsite directory
  * make webdocs EXTRA_PLUGIN_FORMATTER_ARGS='--ansible-build-data=../../../ansible-build-data'
