> I was working on packagin JBoss AS into homebrew (Mac OS packaging system) and found a limitation in our command scripts.
> They assume that the script has not been symlinked and hence fail to find the right jars upon symlinked scripts.
> Basically, they do 
> {code}
> DIRNAME=`dirname $0`
> PROGNAME=`basename $0`
> {code}
> and should do
> {code}
> # Extract the directory and the program name
> # takes care of symlinks
> PRG="$0"
> while [ -h "$PRG" ] ; do
>   ls=`ls -ld "$PRG"`
>   link=`expr "$ls" : '.*-> \(.*\)$'`
>   if expr "$link" : '/.*' > /dev/null; then
>     PRG="$link"
>   else
>     PRG="`dirname "$PRG"`/$link"
>   fi
> done
> DIRNAME=`dirname "$PRG"`
> PROGNAME=`basename "$PRG"`
> {code}
