Watch out for shells with funny 'expansion rules', like csh(1) :)

Even in sh(1) variants, it's always a good idea to save the Perl script
in a file first, and test it independently of the shell, with:

	perl filter.pl < infile > outfile

To avoid all the messy details about single-quotes, double-quotes,
backquotes, stars, dollars, etc :)
