Have just tried the checker. What it does is great but limited: my main
criticism being that it doesn't apply itself to files that are 'source'
or packages. In practice this is a strong limitation since I tend to put
global configuration data into a configuration file that is sourced and
divide up main chunks of work into packages. I also use tcllib quite a
lot and any commands from their packages are marked as unknown. What
would be nice would be to have the checker check everything it can but
provide an option for selectively excluding packages.
