[juneau-lug] recursively changing the case of hyperlinks in html documents

These go along with the previous script I posted.  Once you rename your
files & directories, your existing hyperlinks may not be valid anymore on a
*nix server.  (Index.html is not index.html)

So this paired shell script and sed script will rewrite <A (everything
here)> to all lowercase.  It will leave other HTML tags alone.  You could
expand the regexp to be <[Aa] [Hh][Rr][Ee][Ff] to get JUST the hyperlinks if
you like, or remove the [Aa] to get all tags and any text that happens to be
in <> brackets.

Note that in the current form, it does not test the directory input supplied
by the user (see previous script) and you have to manually replace your
existing *.html or *.htm with the new lowercase link *.html.2 or *.htm.2
files.  This script is mostly copied out of the O'Reilly Sed & Awk book - I
just wrote the regexps.

Cheers,

James
