XMOS Tools with Csh - version switching script

[errordeveloper]

I have had some need to be able to switch between different version of XMOS tools within Csh.

If anyone ever needs this - checkout my gist.

There are two scripts (modpath.csh and delpath.csh) which I use for other things also,
and `xmos.csh` is just for Xmos tools - it's fairly intelligent. I'd be glad to hear if anyone
finds it useful AND no Csh/Bash/Zsh flame wars please!
(Read my blog if you wander why would one chose to use Csh).
