# 1. Using esearch and esummary to Query Genome Size
# You can fetch genome size information from NCBI's Assembly database:
_polap_lib_ncbi-query-genome-size() {
	local _species="${1}"

		grep 'total_length' |
		awk -F'[<>]' '{print $3}' |
		awk '{sum+=$1; count+=1} END {if (count > 0) print sum/count}' |
		awk '{print int($1)}')

	# xtract -pattern DocumentSummary -element species,assembly_name,total_length
