FWIW, sed is a required package and thus guaranteed to be present on any
Debian system, while html2text is optional.
$ apt-cache show sed |grep Priority
Priority: required
$ apt-cache show html2text |grep Priority
Priority: optional
If the job can be done with Priority `required' or `important' tools,
there is a much better chance of the script being portable.
