You can also get a case insensitive sort by using standard sort options
like ``sort -fd''.  The -f says lower case characters into the equivalent
upper case, and the -d says Sort in `phone directory' order: ignore all
characters except letters, digits, and blanks.

Using any LANG setting other ``C'' can cause some very strange results when
one is doing system administration things where I expect a straight ascii
sort.

The first time I ran into this was when I was building gawk on a UnixWare
system when it failed the tests because sorts weren't producing the
expected results.

It is necessary for the welfare of society that genius should be
privileged to utter sedition, to blaspheme, to outrage good taste, to
corrupt the youthful mind, and generally to scandalize one's uncles.
