sh aux/commonmark.sh -N NAME_UC -t TITLE -l LANG [-H HEADER]
sh aux/commonmark.sh -h

help() {
cat <<-'EOF'

-h, --help show this message
Consume CommonMark data from STDIN and emit HTML5 to STDOUT,
using NAME_UC, TITLE and LANG as metadata, and allowing extra
HTML to be injected via HEADER.
Examples:
Generate `index.html` from `README.md`:
$ sh aux/commonmark.sh -N MyProj -t Home -l en -H extra.html < README.md > index.html
EOF
