The fragment above is a series of sed statements used to normalize the
machines architecture. The `.' is a regular expression that matches
any single character, s/// is the substation operator, so
sed -e 's/i.86/i386/'
would match "i386", "i486", "i586" and replace it with "i386", that is
what I meant by "normalize". As it were, it would match "i"<any
single character>"386". I added the quotes around the sed expression
in case you wanted to try it at the CL.
