The conda environment was built as per the instructions here. i.e.,

# You can use "conda create" here instead, if you don't have mamba installed
mamba create -n bioconda -c conda-forge -c bioconda bioconda-utils

conda activate bioconda

# optional linting
bioconda-utils lint --git-range master

# build and test
bioconda-utils build --docker --mulled-test --git-range master
