New files from Ralf Corsepius <corsepiu@faw.uni-ulm.de>. His comments:
* c/src/exec/score/tools/sh - NEW DIRECTORY - contains shgen Most of it should be self-explanatory. I am a little bit concerned about host-dependent features (getopt, floating point libraries). This shouldn't disturb much now, as this tool should be compileable on all gnu-based hosts and is only applicable for the sh. But in case somebody complains, we may need to add autoconf checks or even restructurize parts of rtems (IMO, rtems needs to be restructurized - remember the "turning rtems upside down" issue).
