Re: Customizable filesystem support for GNUstep

[Robert Slover]

To avoid the overhead of starting the Bourne shell just to utilize IFS, 
you can use a csh variable modifier to break the path up on each ':'

foreach dir ( "" ${GNUSTEP_TOOLS_PATHLIST:as~:~ ~} )

instead of

foreach dir ( `/bin/sh -c 'IFS=:; for i in 
'"${GNUSTEP_TOOLS_PATHLIST}"'; do echo $i; done'` )

:a --> apply to all
:s~a~b~  --> substitute string b for string a

(Note that there is a space between the last two tildes, so this 
substitutes a space for all colon delimiters in the variable value).
