If you want to get the path to the main executable on Mac OS X, use
_NSGetExecutablePath. See:
man 3 dyld

An additional sanity check of "topdir" makes sense then.

Simon, as usual, is right. It's been quite a while since I last
seriously coded in C. From the exec* man page:
"The first argument, *by convention*, should point to the file name
associated with the file being executed."
However, if nothing better is found I guess it's better to rely on an
extended convention rather than hardcoding paths.

Well, you can always combine the first argument of the script

I meant _use_ the first argument of the script ($0) for absolute
paths
and combine it with pwd for relative ones.
#!/bin/sh
reldir=`dirname $0`
topdir=`(cd $reldir; pwd)`
There's no guarantee that $0 holds anything reasonable: you can
set $0 to
whatever you like when calling exec*().
Cheers,
