Here they are.
I renamed them 00xfree.* as suggested by Max Bowsher which I thing is 
even cleaner than having other scripts including the XFree script (which 
would mean that the script will have to keep its name whatever happens, 
it would be executed several times, ...).

 From the bash man page:
	Pathname Expansion
		After  word  splitting, unless the -f option has been
		set, bash scans each word for the characters *, ?, and
		[. If one of these characters appears, then the word is
		regarded as a pattern, and replaced with an
		alphabetically sorted  list  of  file  names  matching
		the pattern.

 From the tcsh man page:
	Filename substitution
		If a word contains any of the characters `*', `?', `['
		or `{' or begins with the character `~' it is  a
		candidate  for  filename substitution, also known as
		``globbing''.  This word is then regarded as a pattern
		(``glob-pattern''), and replaced with an alphabetically
		sorted list of file names which match the pattern

So I think we could use this feature to ensure that the XFree script 
will be executed before any other scripts.
